In the meantime, you can edit the linkss/bin/cover-extract
script (with an UNIX friendly text editor, since this is a shell script, and all hell will break loose if it's not using *nix line endings):
Look for -background white
@ L116, and change it to -background black
Also, if my understanding of the process is correct, it should be possibly to take the cached image and manipulate that. I did this with an abstract cover for The Hobbit. Simply inverted it and changed it a little bit, now it looks much nicer on the non-lit sleeping screen.
But such manipulations are beyond the scope of cover-extract. Too much user-interaction required.
I think the default's just fine, by the way.
