Okay, yeah, exactly. I mentioned several times that it was happening to me at low brightness and at night, and I pointed to the lighting a few times too and mentioned it was too bright to see the issue there. When they turned it down to 0% brightness, even I couldn't see the screen so there was no point looking for the tint like that.Sorry for me being so vague. I simply meant that conditions in shop is usually that it is very bright environment so checking issues like this is nearly impossible. And even if they bother checking it in a dark room, they just quickly do that ignoring the fact that it takes a while for eyes to adjust that to be able to even see what you try to tell them.
My phone does not have a cast when viewed from an angle. I want to mention here that I have several OLED TVs at home, and one of them had a really similar issue to what I'm facing with my iPhone 15 PM now, in that a part of the left side of the screen is red-tinted when viewing a white screen or light-colored content. It's especially noticeable for content like basketball games or certain video games that display white screens when loading or in cutscenes. Back to the phone, I did download a full screen white image, but it's not so visible unless it's nighttime when it's really dark. I like to keep my phone brightness low, but even then with auto-brightness setting the brightness quite low, it's pretty noticeable at night and early morning.BTW. Not sure all in this thread are talking about the same issue. My issue is that different parts of the screen have different hue when viewing it straight angle using full screen white image (and this issue shows best when using NS and TT). I'm not talking about color cast when you view it from an angle, which is typical for OLED to show some kind of color cast doing that.
These are some of the better pictures I got of the issue using an SE to take the pictures.
