I haven't actually looked into the music streaming services so I can't say. I know Tidal was pushing quality a lot, but sounds like they're somewhat troubled so curious if they stick around. Plus, I think they're pushing for MQA which I'm not a fan of. I believe one of the other bigger services started offering lossless streaming (assuming your connection can keep up).
The reality is, that's not what is holding back the quality, its that they're starting with recordings that have been mixed and mastered in the Loudness War era. That's not to say there aren't good recordings, but the formats aren't the problem, and they're still flailing around on solutions to falling music revenue.
So, the best answer is, go with the service that has the music you actually listen to or offers the features you want (like recommendations based on the music you like), or fits your situation (i.e. if you're on iOS or Android, where/how you do your listening, etc).
