Here, too.
Eink contrast ratio is pretty much maxed out.
Part of the problem is the globe material: it covers both the black side and the "white" side so it makes the dark side lighter and the light side darker. Front lighting helps a bit. Backlighting would help more but at that point you might as well go LCD.
The way display technology is evolving I think microLEDS will take over whatever dedicated reader market remains starting around the middle of next decade.
