The default maximum cover image size is no longer appropriate at 1200x1600. With hi-res eInk screens at a resolution of up to 1872 x 1404, the default should be increased to mach today's 300DPI eInk resolution.

Also, would it be possible to modify Calibre so if it sees the default values that it automatically updates that to new higher values? I know the defaults can be changed for new installs, but that does nothing for existing installs where these values really should be changed.
