There’s maybe a billion-dollar opportunity there: maybe someone could invent a hybrid screen that switches from (O)LED to e-ink mode under bright lighting conditions.

That's exactly what OLPC has. And I remember an old Nokia phone having a screen that's both at the same time so that brighter sunlight will just wash out the colors but not the content: https://en.m.wikipedia.org/wiki/Transflective_liquid-crystal...

Somebody did invent a hybrid screen, Pixel Qi, it was used in the Notion Ink Adam tablet from 2010.
But it wasn't a billion-dollar opportunity and Pixel Qi are so forgotten they were reported by the media as closed down, although might technically still exist (and might have released their IP to the public, I haven't read too far on it just now).
