I was in the AT&T store today and checked out the only 2 13PM and 13 Pro they and they both had good screens from what I could see without a dark room.
its impossible to see these defects on day light. i dont even know if i should call them defects anymore, apparently thats how these screens are. Its a spectrum of anoying details from slight red tint on the sides that barely affects regular use to heavy red tint on light and/or dark modes.
Now that looks straight up defective. Your others looked in the margin of error. I haven't seen one yet (of any posted on this site) that didn't look like it had at least some minor variance. I think some of the greys are just hard for OLED to reproduce and they fail over to too much grey or red.
Ok, i got and checked my 6th and LAST iphone 13 pro max, this time i got the sierra blue one, and side note these seem to have no chips or scratches out of the box like the rest. I guess the process makes it a bit more resistant.
anywaysssssss, this red tint issue affects these devices on white or/and dark modes.
this unite had its pinkish tint on the left upper side disappearing down to the center of the phone. it made the settings menu very non-uniform, but when you checked on whites it seamed kinda uniform with a cold tint all around and a hint of pink on the lower area.
compared to my keeper iphone 13 pro max it looked better under 10% brightness on light mode but above that mine looked as perfect on whites with a more all around warmer tint. mine on the other hand looked much better on dark mode with an all around uniform grey with just a hint of pinkish tone on the right side. far better and less distracting.
but my phone (keeper) didnt look as uniform on white screens under 10% brightness in a dark room but is still great and uniform when used anywhere else.
conslusion.... choose your hell jejejjeje
just pick the one that bothers you the least and stop looking for a perfect one... if it doesnt bother you in normal use DO NOT CHECK FOR DEFFECTS!!
THE PINKISH TONE IS NORMAL ON IPHONE 13 PRO, and apparently is somewhat natural to the tech used this year. i guess the screen under performs in low brightness conditions specially under 15% brightness in dark rooms.
i hope this helps... 😃🤝
