For what it's worth; that first image looks like a defective screen to me.

I THINK it is an image of a GRAY SCALE. It shows the gradations from white to black.
As for the original issue: I don't believe the screen was intended to be used in that manner - all black or white or even blocks of those "colors". It is intended as mentioned, to display text. The "mottling" is because there are "pixels" (or whatever they are called in e-ink).
It does a reasonable but not great job of showing my photos where there is reasonable contrast, like scenes with snowy mountains. Grassy meadows with the gray mountains and cloudless blue sky are less than striking.
