>The weird thing is that we already have “foldable screens.” But all the phone makers have done with them is to give us slightly less bezel on our glass rectangles.

Also, aren't they used for curved TV screens and computer monitors?

Sure, these displays are bendable. But they have a zero Gaussian curvature everywhere. What would be really interesting is to build a flat panel display that has a non-zero Gaussian curvature at will, e.g. one that fits into the windshield of a car.

There is a catch that programming these displays require one to learn differential geometry as a prerequisite.
