MIDI encodes very little information about timbre, which is a huge source of variation in modern pop music.

Very little? More like none.
Program change + general MIDI instrument set is implementation-dependent but was pretty common in the 90s, and encodes timbre in an extremely limited way. Now of course nobody outside of fringe artists really use it.
it got very basic description in form of instrument index, so program 0 is piano, 4 guitar and so on.
