First of all, AirPlay is a proprietary wireless communication protocol / stack.
If you're not up on the technology of communication protocols then some of the following quote from the Wikipedia AirPlay entry may be gobbledegook
[see the entry for more and for references]
The devil is in that phrase "transcoded using...." One might think that since ALAC is involved everything will be lossless but apparently not so with Apple Music (and I have no idea how many other apps). It's all proprietary so good luck sorting it out.
Just my 2-cents worth.

Quote:The AirTunes [e.g., the audio] part of the AirPlay protocol stack uses UDP for streaming audio and is based on the Real Time Streaming Protocol.[24] The streams are transcoded using the Apple Lossless codec with 44100 Hz and 2 channels symmetrically encrypted with AES, requiring the receiver to have access to the appropriate key to decrypt the streams.[25]
