So a couple of cups of coffee and several distractions later, I came back to this point.
I note the shairport-sync documentation includes AIRPLAY2 in which it is stated "Lossless and High Definition Lossless material is transcoded to AAC before it reaches Shairport Sync." This same is to be found in an earlier github issue https://github.com/mikebrady/shairport-sync/issues/1205
It seems to contradict the Wikipedia entry which states the transcoding is done with the Apple lossless encoder but perhaps that was talking strictly about classic AirPlay and not AirPlay 2.
Finally, according to the docs, shairport-sync can be built with the option to use the Apple ALAC decoder (requiring libalac). It isn't clear to me that the executable included in moOde includes this option. OTOH, I don't know what happens when this option is or isn't included.
Color me confused.

Kent
PS - fortunately, between the overall quality of my audio system and the condition of my ancient ears, I don't find playback via moOde's Airplay renderer to be noticeably different.
