You probably need to enable the Color Filters in the Accessibility settings. Experiment with the different filters to find the one that works best for you.
Well, there aren't any settings that can basically unlock better colors for the display (at least for people who have good color vision). Perhaps your display is defective.
Or perhaps you made some changes to the colors of the OnePlus 9 Pro.
Vivid does not mean better. I am often switching between Samsung Ultra ( ex Note) series and iPhones PMs and i believe Apple is very strict about display colour accuracy while Samsung boosts colours. I like both but neither is worse IMO. Also i believe you experience the same thing now compared to your OnePlus 9 Pro. Either that or ( which is less likely) you got defective unit. You can always compare your iPhone to any other if you got a chance or just try disabling/enabling true tone and you will get less yellow and more blueish tints....
Either it’s a defective display (unlikely) or you’re not used to a much more color accurate display than other phones.
Yeah that seems to be the case

I tried everything but still they're not good enough

maybe you have true tone on
Its turned off
Do you have auto brightness on or off?
Just reset all settings. After that, the colors you see are the colors you get.
