(Don't mind the crazy path to the colour map, I'm on a laptop, the file is shipped with the hack).
(The same kind of results can be achieved with any decent image editor, if you're somehow allergic to CLI  [But, FWIW, I just did that on OS X with IM installed via Homebrew]).
TL;DR: Yes, it usually ends up looking way better than what the default reader does, but it's also an order of magnitude slower . |
Thank you so effing much!
Weird thing though: when I uploaded the image you dithered (that word makes me giggle) to the Kindle inside the book, it looked pixelated again. But I manually changed the cover generated in the cover cache folder and now it looks PERFECT. Was Calibre to blame for the pixelation?
