I have noticed something similar but due to the low (in comparison) contrast of E Ink displays.
As an example of the effect of contrast in another field, it is a common practice in photography to use contrast to make parts of the photo more distinctive ("clearer", "pops out"). For example with a photo of a bird one may when developing the image (in Lightroom, for example) one increases the contrast of that part of the photo that is the bird. This does 2 things, the bird becomes more distinctive against the background and the various parts of the bird (feathers, eyes, etc.) become more distinctive on the bird.
This same effect applies to fonts on displays. So, I find that with LCD/AMOLED displays I can read easily much more delicate and smaller fonts on them that on the much lower contrast E Ink displays. Also, I find that I also can read "normal" fonts in much lower light levels on them. The much better contrast makes them more distinctive.
Not much of a problem for "normal" fonts and size with a novel, but even so quite noticeable when used to more competent displays.
