That is correct. Similar to Airplay, it's lossless over an encrypted session so 10x better than BT.
"protocol stack uses UDP for streaming audio and is based on the RTSP network control protocol. 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. The stream is buffered for approximately 2 seconds before playback begins,"
