What is TrueTone display settings on your iPhone?
You can turn on True Tone*, which uses advanced sensors to adjust the color and intensity of your display to match the ambient light, so that images appear more natural.
You can also turn on Night Shift, which adjusts the colors of your display to the warmer end of the spectrum — making the display easier on your eyes.
Some display accessibility settings, including Invert Colors, Grayscale, and Increase Contrast, might turn off True Tone.
