Well, as a remote I'd expect you'd not have to CHANGE the screen often, which is where eink excels. I don't sub-sub-sub-menus on my remote. I want everything directly available, and presumably some sort of mode switch to toggle between my different devices. If you combine details from one devices (TV power on, volume Up/down) with another device (roku controls) on a single control screen, then I would only rarely have to switch modes at all.

I've been waiting to see eink used in more places - I recall reading that India had non-smart cell phone handsets that used it for the screen, which seemed a great purpose (display time/date, incoming call number, outgoing call number, none of which require rapid changes in display), but not hearing that it had really gotten anywhere else.

It also doesn't help that there aren't a few tactile buttons for frequently used tasks like FF, REW, Pause, Play, etc.

If you're controlling any type of media player, it is always nice to have those buttons available so you don't have to look down at the remote to input an operation.
