Some of it is probably adaptive vision.

My Pixel 6 with an OLED screen doesn't work very good as a walking light in a dark room.

Also a Pixel owner - Try wiggling the light as you walk.

Your motion sensing kicks in before either your focus or dark vision, and even if you can't "see" it, your brain can get enough information to let you navigate.

I pointed that out because it is pretty dim, I don't try very hard to use the screen as a light.
