For sure
There's very few wireless speakers that will do full high res audio, and the ones that do, I'm not convinced any really have the expanded range given their configuration. Just the pixel war all over again "our speaker has bigger numbers than the other guys speakers".
Airplay tops out at 24/48 with (dual) Homepods anyhow. There's not alot of music thats going to benefit from anything higher, fewer people and seriously doubt it's anyway noticeable anyhow on common consumer speakers.
Lossless Airplay playback however though (even 16/44.1) is a huge step up from the sloppy mess of bluetooth (especially at any kind of distance) and is a benefit on capable speakers.
Maybe the reason Spotify don't want to add AirPlay support is because of just how bad many of their rips sound when compared to Tidal / Pandora or Apple music in an Apples to Apples competition?
