As I wrote, this was kind of expected (to me anyway).
iTunes/Apple Music on macOS has had this issue for years, with local hi-res content too.
Lossless streaming has been pushed out early to get a head start on Spotify HiFi…
So I expect proper auto sample rate switching later. Maybe next macOS version end of the year.
And new hardware (eg headphones) will come out to take better advantage
Remember this is a free update for existing Apple Music customers, so the complaints need to be put in perspective lol
Yes see my screenshot I shared earlier.
