iPhone 14 screen tint when tilted

I doubt that it is an issue; How tinted does it get? there will be a slight change in color as you are viewing the colored pixels from the side (the image is composed of pixels of 3 different colors that your eye integrates into the color palette you see). Is this an original screen, or one replaced by a shop other than Apple?

Try checking ur settings, standby and then display. I know the night mode changes the screen color when tilted on side.

Literally all LCD and LED screens shift hue and brightness when tilted. The only current screen type that doesn't is OLED, which the iPhone 14 does not use.
