Well, it's not compressed, it's generated. You could generate an endless video with less code, but it would most likely be uninteresting. Scene demos are interesting because it's art and direction and music generated from algorithms rather than creating those things and compressing them efficiently.

But, yes, at some level there is an idea of a dna seed and a process to create something much more profound, we as humanity haven't come close to cracking that, though.
