True Tone and photo editing apps : change in white balance when using these apps ?

[MayaTlab]

Hi, I've noticed that when True Tone is on, the white balance reverts back to a colder temperature when I'm in photos / video editing apps.

This can easily be noticed when quickly switching between a photo editing app (ex : Apple's Photos, Adobe's Lightroom) and a non-photo editing app (ex : Notes, Settings, etc.) with the multitask UI (swipe from the bottom). When I switch to, let's say, Lightroom, the True Tone icon still stays on, but the white balance switches to a colder temperature closer to what the screen looks like when True Tone is off. Switching back to another app (ex : mail), the color temp switches back to what it normally looks like when True Tone is on.

Is that a normal behaviour ? it would make sense, as photo editing relies on screen calibration and colour consistency to an extent, that True Tone would be less aggressive in these apps, but I just want to make sure.

Thanks in advance for your inputs !

Haven’t notice this, I turned off true tone when using creative apps.

Yes, it's normal. There's actually an API that developers can use to tell iOS what kind of app they are so the True Tone adjustment isn't so severe. It's called UIWhitePointAdaptivityStyle.
