Amazon prime music launched with high-res also.

Really makes you think. There are quite a few blogs that open “high-res” releases in a spectrum analyzer and point out where the frequency cutoff is. They just re-encoded the original without any remastering.
Spotify went for the bigger market instead of the small niche of dubious gains. Can’t say I blame them. They have a lot of competition in 2024
