You're writing some kind of pixel data for all pixels on the screen at 50 fps on an eink display? Seems unlikely.
Also, what you described takes neither memory (1-4 bytes/pixel seems enough) nor time (small LUTs seems enough).

Yes, of course you need some kind of frame buffer or blitter or whatever. My point was that this custom chip should be as generic as possible instead of implementing specific high level concepts such as menus or whatever. At least until it's been shown exactly which things are too slow (or takes too much power) to do in software without specific hardware-acceleration.

Well, at least it's good to know they didn't just do internal testing.

Not only that, but having certain very specific things optimized might steer the way of the future development into a bad direction. The recovery of such a thing often takes lots of time (but might make some company lots of money), during which the endusers will have to endure needlessly bad readers. I'm very pro-enduser, so I tend to criticize things that might be bad for endusers (even when I'm part of the dev team and thus get to suffer the heat of my own criticism).
OTOH, the optimizations might turn out to be very good, and in that fortunate case => happy happy joy joy
