\$\begingroup\$ Too bad you didn't win the bounty, I was really hoping an approach like this would take it - I've given you an "honourable mention" in the question. I'm looking forward to the explanation of how this was produced. \$\endgroup\$

\$\begingroup\$ @Nathaniel I may have just missed the bounty by hours; my optimizer is still running, and I just reached 5000. \$\endgroup\$

\$\begingroup\$ Well, you might be in luck - I already announced a second bounty if an optimisation based approach takes first place among the non-compression based answers. (See the updated question text.) \$\endgroup\$

\$\begingroup\$ Heh, I was out to beat Sleafar (and he would have won anyway, since his score is lower than yours). Was quite surprised that the change I made (disabling dithering) made such a big impact. \$\endgroup\$

\$\begingroup\$ +1 for Voronoi and for using a subplane of the RGB cube. Did you try using any of the answers from codegolf.stackexchange.com/q/50299/8478 to optimise the Voronoi diagram? (Of course, those were aiming at visual similarity, not minimising an objective error, so YMMV, but I think some of them might yield pretty good results.) Also, have you tried using just a line through the RGB cube so you can use twice as many Voronoi cells? \$\endgroup\$
