display – Does MacBook Pro (2019) screen brightness change when you look at it?


I was wondering if MacBook Pro automatic brightness adjustment would adjust based on whether you are looking at it (also called attention in the iPhone I believe)?

I noticed this when using my MBP in battery mode, it would dim (a lot) when I am not looking at it, and then brighten back up (takes like 1s to increase the brightness in a few stages) when I start looking at it (i don’t even have to move the touchpad or hit the keyboard).

Does the ambient light sensor have this functionality?
Or maybe when I look at it my “image” is bright/dark to the ambient light sensor so it changes the brightness accordingly, and correctly in this case?
