I've also noticed this on my Google Home/Nest Hub, where it has an effect where it adjusts the image on screen to match the color temperature of the ambient light. It makes for a really weird (albeit pleasant) effect that to my eye makes the image look more like a printed/reflective image. I've long wondered if you could duplicate that effect by replacing the backlighting in a junk LCD with something that can adjust color temperature and adding a color sensor, but haven't had time to try it.
