True Tone isn't a blue light filter per se, but that more or less is the effect it has. A simple way to think about what True Tone does is to look at a window that has a lot of white in it. Next look down at your desk at a sheet of paper. True Tone basically uses the light from the room to adjust the white balance of your screen. Without True Tone turned on, the white on your screen will be white and the 'white' of your paper will be the color of light in your environment. When you turn on True Tone, the 'white' on your screen will be very close to the 'white' of your paper.

Personally, I do not use True Tone. It does nothing for me, but others love it.

Apple True Tone

Nigh Shift is more akin to Apple's blue blocker and is designed to decrease blue light levels throughout the day because research indicates that too much blue light late in the day can adversely affect our ability to fall asleep at night.

Personally, this is another feature that I do not use.

I guess I prefer the predictability of having my screen look the same across devices and throughout the day. True Tone may not be that bad. I'm sure I could get used to it, but I have a Mac mini as one of my daily devices. Only a laptop with the lid open to expose the light sensor can drive an external display and apply the True Tone filter.

Interestingly, I happily use TrueTone on iPad/iPhone, but can't stand it on Mac.
