I'm ignorant of EInk technology, so thanks for bearing with me.

As far as I know, you don't change the brightness/contrast of the eInk screen itself, which is fixed; you just change the translation of images' colours to gray levels on the screen. Basically, it's like changing brightness/contrast in Photoshop (or whatever), not in the monitor knobs.
So yes, your description is right.
