I've never dithered cover image, so never seen banding.
Used covers "as is" on Kobo Touch, Original Aura H2O, Libra, Libra2, Sage and Elipsa.
Dithered would want to be PNG, as JPEG can make a mess of dithering anyway. A dithered image is a disaster to rescale, so a dithered image only suits something than can do the source to display pixels 1:1.
