Mentioned many times.

That's threshold. It's very easy:
if pixel>GREY then return WHITE else return BLACK
Easy and fast - of course, it's also naive.

When a naive rendering would give homogeneous bands but the idea is to render a gradient, so you have to gradually mix the two, that's dithering.
You could remember the term from graphics processing software and interfaces relevant to palettes - e.g. conversion to fewer colours, GIF, etc. It was more frequent when we had less colours...

I would have guessed that a 2017+ firmware may have implemented the feature...
I am pretty sure it is in the firmware, not in the hardware.
