Music app streaming quality on Apple TV

I have an Apple TV connected to my my home theater for movies, TV and my Apple Music library. When using Apple Music on my Mac or iOS devices I can specify the quality of the music stream (AAC, Lossless, hi-res, etc.) based on my connection. When using the Music app on the Apple TV, I don't see a way to set the quality.

Is there a way to set the quality of the stream?

If not, what is the default quality of the stream? Please don't say AAC.
