Probably not. e-ink displays are much more expensive than a cheap $200-300 "smart" TV mounted to the wall. A 31" display module (not the stuff to drive it) is $2300. Maybe you can get the price down in bulk purchasing, but a 40" TV could be purchased for $200-300 right now from any big box store. So an array of 6 40" TVs displaying menus would be cheaper than one of these.

Commercial displays are more like $700-$1000 in this size class, and power isn’t free, so there is presumably some crossover point in total cost of ownership.

I’ll gladly replace my menuboard 43” TVs with eInk displays if they ever reach the rough price neighborhood ($1500?) and have a single-digit-seconds repaint time

But will you feel silly for choosing, say, 2x$1000 displays versus 1x$2300 smaller display today? Probably not. Which was what I was responding to. Should the price ever drop enough, then sure, it would make sense at that point to select an e-ink display. But it's a terrible choice today, so nothing to feel silly about.
