Ok I'm confused now. So is this thing considered epaper, eink, both or neither?

Is one a subset of the other? If so which is the superset?

E ink is a trademark name for electrophoretic displays (magnetic particles) by the company also called E ink.

E-paper is an informal category that anyone can use for any display type.

The display in this video/article is also electrophoretic, but not all displays called e-paper are and it’s aggravating. An example: https://kentdisplays.com/products/color-epaper-displays/

if this display is one that everyone understands is epaper then what's the problem

> if everyone understands ... then what's the problem

"E-paper" means very little. It may mean "static" (and yet not necessarily "bistable", not even necessarily "efficient"), it may mean "reflective"... It is a marketing term.

So no, there is no real "agreed understanding" in it.

It's not just a marketing term. Everyone agrees that it means reflective screen, with reflectivity somewhat approaching real paper.
