@(Unverified) So the deal is that the pixels can only display 4 levels of gray, but the pixel density is tight enough that by placing a dark pixel next to a medium gray will appear to be a shade somewhat in the middle.It has more to do with how many pixels are actually darkened in a given area more than the darkness of the pixels themselves.
This is actually extremely common outside of e-readers. Next time you get your hands on a newspaper, go to one of the black-&-White pages and take a look at the picture. It looks like a pretty smooth gradient at a glance, but if you take a magnifying glass to it, you can see that only one shade of black was used to make the picture, and that the lighter sections just have fewer black dots. However, the dots even in the light gray sections are still the same color ink as the ink used in the darkest part of the page.

Four levels of grayscale sounds like an 'industry worst' but the picture looks nicer than that. Hard to say at that angle/scale.
