The original cover is 2000 x 1250.
I don't think that is the issue, as kindlegen resizes the cover to 1270x794, both for the old format and for the new 8 format (there are 2 sets of files in the mobi). When I open the mobi file then open in the Kindle full screen, but in the Fire with a margin around it.
So it definitely has to either be something specified in the '8' files, or, and I'm thinking more likely, the Kindle software treats the '8' cover differently.
