I have recently ordered a Kobo Clara HD, so I've been liberating and converting a number of my Amazon books in preparation. When reviewing one book, I noticed that some of the graphics were significantly degraded, for example:

It looks like the image might have been re-encoded, and the lossy compression either added artifacts, or has a higher compression setting. Are there any settings that I can modify to improve this?

The cover doesn't seem to have suffered the same fate, just the in-book image(s).

EDIT: I've tried the tablet and HD eInk page layout profiles, neither helped.
