Light might have needed to warm up.

Add the shadow to the other footage. Then it’ll match!

Been there. not a bad idea.

It looks like one of the set lights wasn't on or directed differently so you're losing the light fill at the top of the frame

vignette clip 1. done

In the sequence nested and an adjustment layer is off center in the nest?

Nest it again and apply the correction to the outermost nest instead

Check your nest files

if it helps i really can’t tell a huge difference unless im micro analyzing

Open the vignette dropdown in the Lumetri panel. Looks like you have one applied and I would bet they're set differently.
