True Tone

True Tone feature is supposed to match your iPhone's screen in relation to reality and more natural appearance. You will get somewhat of a light yellow tint especially in darker conditions.

The other option that creates a yellow tint (heavier than True Tone) is the Night Shift Feature. Ensure that this is set to OFF.
