Just bought an iPhone 15 Pro Max and noticed some weird faint vertical lines on the display. I first noticed it during regular use, and then used a plain white image with the brightness turned all the way down to see it more clearly. The lines are faint, but definitely there. I also noticed that the top half of the screen appears slightly darker than the bottom half. I'm guessing this is probably just some OLED panel inconsistencies and a result of Apple's lacking quality control… How does your screen look?
