My REDMAGIC Android phone is like this too and I love not having a stupid notch cut out of the screen. I've hated them since the very first time I saw a iPhone X. Can't believe such a ridiculous design defect infected Macbooks too :/

do you have a picture of what that looks like? having a hard time conceptualizing that.

It's not visible at all. The camera is just placed behind the screen.

OLED screens are inherently transparent, there is just a light-emitting layer in them. You put your camera behind the screen, and either make the few pixels on top of the lens go black when it's on, or you use a lot of software to remove the light that comes from the screen and clean up the picture.
