Slightly off-topic, but modern e-books tend to be eyesores. You would think that with image formats able to encode 10 bits or more per-color and CSS[^1], and all the features digital fonts support these days, people could do a bit better.

They could, but then they will only work on tablets and not eink readers...
Printed books as well. Go to Barnes and Noble when you get a chance. Almost every book in the store looks like it was printed on the same low quality factory equipment using low quality materials, almost like they were all fake.
[^1] E-pub allows CSS.
