In person it looks very even with no noticeable colour cast, based on what I’ve seen here I got lucky on my first attempt for both screen and build quality.This screen actually looks pretty good with only some color shift from top to bottom, nothing egregious like earlier posts. Are you seeing anything in person?
I've noticed a trend where 13 Pro displays seem to be less affected than Pro Max too.
This is the first iPhone I haven’t had to exchange at least once and I have owned every generation including the original.
