ah, that is an excellent idea.
I wonder if/when they'll actually emplace a camera behind the display itself, looking through the display. This seems impossible now with an optical element, but if a sensor was an array of sensors with micro-optical elements, it could be distributed over the surface of the display and then software would produce the image... looking at the screen would be to look at the subject.

Couple of Android phones have experimented with this although not sure any have been commercially released yet

Did you see this last year? It was in the iOS 13 beta but it seems like they pulled the feature in the end.
