There is nothing about MP3 that harms the high subliminal frequencies in preference to any other signal degradation you experience through compression. All it really takes to prove that is to open an MP3 format subliminal file, and re-shift it back into the audio range to see what you get.
I've done that with any number of files, and aside from making sure you amplify it if needed to have enough signal to work with, they've all been pretty much intact. You do, of course, need to set your decoding shift to match the upshift frequency. (That frequency should be readily identifiable through an analysis chart.)
Naturally, that doesn't speak to the mechanism by which it is perceived by the brain, but I'm wondering if there is some latent sensory mechanism in the human brain similar to that used by bats and cetaceans (dolphins and whales) that can accept this level of input.
