One strange if not entirely unpredictable aspect of Apple Music is the inability to set the streaming audio quality. In fact, there's no hint of the streaming bitrate anywhere in the app (though you can see that Apple Music tracks are stored as 256kbps AAC files in iTunes).
But it seems an update to the streaming service, which is set to come with the release of iOS 9 later this year, will allow you to have a level of control - specifically, the chance to force Apple Music to stream at the highest available quality when you're streaming over your mobile network.
This relates to the fact that Apple Music streams at a variable bitrate, with Apple exec Eddy Cue admitting the service would lower the audio quality if you have a poor network connection.

This update, which has been spotted in the latest iOS 9 beta by Apple Insider, still keeps the level of control to a minimum, however.
For example, there's seemingly no option to set the streaming quality over WiFi, no hint of the streaming bitrate that you're getting, nor any option to set the audio quality to low, medium or high, as is the norm on the likes of Spotify and Tidal.
As it is, we're 99% certain the service is streaming at 256kbps AAC, which we're happy to report delivers pretty decent audio quality compared to its main, non-lossless rival, Spotify.
Apple iOS 9 is expected to be released later this year.
