> "E Ink" is just a brand of e-paper

It is not. It is a brand of electrophoretic display, which is a type of e-paper display.

> There are other brands that utilize the same technology.

There are not. Not any significant ones anyway.

> Unless specifically noted otherwise, you can safely assume that anyone talking about "e-ink" or "e-paper" means the kind of display used in Kindle, Inkplate or the art frames this article is talking about.

No you can't. "E-ink" displays are definitely e-ink. But an "e-paper" display could be e-ink, transflective LCD, or anything else. There are real products that use transflective LCD and say they have "e-paper" displays. The Pebble watches are the obvious one (sadly discontinued).

There are tons of e-ink products that are described as having e-paper displays which probably contributes to the confusion, but the meaning is quite clear.
