I have one of these, and only in a very specific environment is it convincing as not-a-TV (aside from the concerns of privacy and their proprietary app).
Especially at night, I find the backlight makes it painfully obvious that it's just a TV and I'd much rather have something like e-ink which blends into the surroundings.
While true, I think the original complaint about the backlight was more about the fact that the TV is emitting light, which a picture doesn’t do. OLEDs don’t solve that problem unless you want to display a black square.
