Apple Music got a big bump over Spotify today by dropping lossless and Dolby Atmos streaming.
If you have the lastest Apple software updates, both options will be available, though you will have to switch out AAC streaming to lossless in settings to get that audio option. You will also need to turn Atmos "always on" so your non-Airpods/Beats can use it.
Apple says its entire catalog will be lossless by the end of the year. Less Atmos tracks will be available but more are coming.
