I haven't really heard it being used like that, always heard e-paper being used as the specific e-ink displays and never anything else. The only time I've seen the (in my mind) confused messaging is on Pebble's own website, I still have my original Pebble Time somewhere, and that's a good part just down to how much I love those displays. I don't think I'd have used one for years if they were epaper.

Yeah, other wearable manufacturers who use the same display technology usually call it MIP instead. Pebble are pretty much the only ones who call it e-paper, which has led some to think theirs is a distinct thing, but it's just MIP.
