My point was, just like on your device, using a warmer color reduces the amount of blue light that you’re exposed to and the last three in that picture comes in both, warm and cold color variations.
No clue why it says infrared, that would mean your device was emitting infrared, which it’s not.
If you want to see for yourself, look at your device through the camera of another device, infrared is visible with those. You’ll see the faceID cameras going off but nothing from the screen.
