So reading up on alsa, turns out the "SPECIAL" encoding format is referring to DoP.
Enabling DoP in the mpd config makes that DSD indicator light up, this was unexpected as it works with native DSD on USB Audio Player Pro but there it is. At least mpd doesn't need to convert it in software now.
Thanks again.
