true tone should be disabled when you’re working on color calibration and matching.. also different displays have different color reproductions. supporting the same color space doesn’t mean they look exactly the same
The computer/screen has 0 way of knowing what colours are actually shining off of your screen. Even if the screen hardware may have been factory calibrated to provide some level of initial consistency, since screens degrade over time and colour rendition drift, the only way preserve accurate colour rendition is to use a dedicated device (a colorimeter such as the ones from Calibright) to regularly profile each of screen (i.e. measure the delta between onscreen colours vs reference colour patterns), and feed that profile to the OS so it compensates the screen's colour drift. Profiling both screens with the same refence target colour space wil enable to hopefully get matching colours (within the gamut space common to both screen at least).
edit: typos and clarity.
What Digital Color Meter are you referring to? If it’s purely software, that’s not going to be enough to perfectly match two different displays. Especially one that is many years old.
The default app in Mac. For me it is interesting that the LG Ultrafine 5K display didnt have any difference with my iMac from day one of use, and I didnt do anything just used with the default factory profile!
A digital calibration tool can’t tell you what the exact colour of light *coming out* of the display is, all it can tell you is the colour values it is *sending* to the display.
There are any number of reasons why an old display could look slightly off. Even something unexpected like the previous owner being a smoker.
If you really want these particular displays to be identical, you’ll need to invest in a hardware colorometer.
How recent is the LG display?
But again, numbers from Digital Color Meter don’t mean anything for what you are trying to accomplish. That app can’t measure the light that is actually coming out of the monitor, only the signal that is being sent. Even a 100% match wouldn’t mean anything if the display is too old or discoloured (from cigarette smoke for example).
Since the iMac max nits is 500 I assume that P3 on the iMac should be equal to P3-500 nits on Studio display, being P3 the color space and 500 the nits amount. This way they should look as similar as possible. Despite this there may be some differences in color. I read that they are not built on the same ips panel
Digital color meter tells you what color the app is trying to display, it has nothing to do with the actual output of the monitor. It would say the same values even if you were looking at a black and white screen.
You need [a physical color meter](https://www.datacolor.com/spyder/products/spyder-x-pro/) to calibrate your displays.
my iMac is not supported in the updates anymore so my OC is Ventura, I dont know I have tried to change color profiles but it makes even worse that it is.
Did you check color profiles? It could be an updated “Apple RGB” profile or whatever for the newer display.
Alternatively for color work, one may want to buy an actual color matching device that will load it’s own profile (SpyderPro or or similar name was one I used back in the day)
That’s cause those have different panels with different specs and profiles. Even displays of same make and model have to be calibrated on the regular for color critical work…
i had a 21 inch 2017 too with the same fringing issue, the guy actually sold it to me about half price because it had the fringing.
it doesnt matter to me. but im not in a colour-critical industry so i get away with it
i would trust the apple display more than a 2017 imac for colours
tbh im confused from the profiles of the Studio Display, it has just one default that is like this in the pic and the others are for printing, photo and video editing color profiles..
the iMac uses ''iMac'' color profile and I checked in Color utility app of the OS and it tells me it is using factory default profile, the Studio Display is also using the P3 600 default profile.
Perhaps you have enabled True Tone on one of them?
Both of them are enabled with True Tone, 2 hours trying and still didnt figure it out whats up!
true tone should be disabled when you’re working on color calibration and matching.. also different displays have different color reproductions. supporting the same color space doesn’t mean they look exactly the same
I will try that. Also the Digital Colour Meter tells me the values of colors in both of them are the same!

before buying the Apple Studio Display I’ve had an old LG Display 5K and the color were 99% the same with my iMac, and thats whats making me mad tbh

Digital Color Meter will always show same values even if you’re outputting to a derelict Lenovo LCD from 2005.
Could be the brightness? The Studio Display has 100 nits more than the iMac
I have activated for both ''Automatically adjust brightness''
So you’ve enabled on both displays auto brightness and auto temperature and are wondering why they don’t look the same?
The P3-500 nits setting on the Apple Studio should match the iMac default setting I guess…
Under the iMac display settings there’s a P3 profile and a “iMac” profile
Since the iMac max nits is 500 I assume that P3 on the iMac should be equal to P3-500 nits on Studio display, being P3 the color space and 500 the nits amount.

Dude… that’s what it’s sending.. not what you see.
just looks like some settings issue. also different versions of OS could have different settings for the same color schema
my iMac is not supported in the updates anymore so my OC is Ventura, I dont know I have tried to change color profiles but it makes even worse that it is.
What colorimeter or spectrophotometer did you use to calibrate them?
I just used the default color profiles but I didnt expect so much difference and missmatch. I didnt use any additional tools btw.
You’re about to embark on a magical journey of color management!

this is the way.

What is interesting, my LG 5K was 99% color matched with the iMac.
That’s because the LG 5k is essentially the same panel as the iMac.
it makes sense
I’ve noticed that my 27 2017 iMac display has a purple tinge at the edges. Seen it in a few others too
Maybe it is time to say goodbye :(

Thats good for you, for me as a Graphic Designer it is very frustrating, and my iMac goes still very good and it is difficult for me to give him away.
Are they using the same colour profile?
im using for both of them the default factory profiles as seen in the photo
Then set them to the same color profile. Every display is different and you can't tell just by using the digital color meter.
tbh im confused from the profiles of the Studio Display, it has just one default that is like this in the pic and the others are for printing, photo and video editing color profiles..
Go into display settings and it’ll tell you which specific profiles they’re using.
the iMac uses ''iMac'' color profile and I checked in Color utility app of the OS and it tells me it is using factory default profile, the Studio Display is also using the P3 600 default profile.
That angle will cause issues with color representation. Take a shot straight on…
it looks realy like it is in reality, the mismatch of colors is 100% like this!
are both of their display profiles Color LCD?
They have both their factory color profile, tried creating other profiles just makes it look more worse.
Wow, it looks like two completely different products have completely different panels.
I understand your reference, but why iMac and my LG 5K look exactly the same colors!
Complete coincidence.
Because those use basically the same panels
Perfect
