Based on what I’ve seen so far, this is my conclusion to date:
The XSes screens are of a warmer temperature than X/8/7. It’s almost impossible to find a XS screen to be the same as X/8/7, so it’s pointless to run around hoping to find one to match a X/8/7.
(Even then, there are variances among the X/8/7).
Having said that, among the XSes, there are variances, from slightly warmer (but still looks acceptable, just a different temperature, not necessary “worse”) to grossly yellowish and unacceptable.
So, the question is, has anyone found a XS that’s exactly the same as X/8/7? Are there XS screens out there like that? Or we simply accepted a slightly warm, but acceptable screen?
If Apple has on purpose, changed the white point, to be more easy/heathier on the eyes, etc, then well, we either accept the XS like they are, or buy another phone.
The problem here is the seemingly wide variances among the XS screens.
Oh well.. thought I didn’t have to go through this, after more than 6 generations of iPhones.
