What is iPhone True Tone?

iPhone true tone, Apple’s official description is “uses advanced multichannel sensors to adjust the color and intensity of your display…to match the ambient light so that images appear more natural.”, but it is actually adjusting the white balance of the screen according to the ambient light to reduce eye irritation, but this is definitely will affect color reproduction. An extreme example is the night view mode, the entire screen turns dark yellow, which is indeed more comfortable in the dark, and has nothing to do with “color accuracy”.

No, because we often restore the true tone function. This technology has now been popularized.
