This is pretty much on the money. Note that Roon will still display the highest quality available next to the album, because we don’t have that kind of granularity of metadata. Signal path will be correct though and show what is actually being streamed.
That would be one use case (and clearly we have customers who want to do this), but in general, being able to control the streaming bandwidth is the important consideration, for both TIDAL and Qobuz. You may need to restrict Qobuz to 24/96 or TIDAL to MP3 when in a hotel, for example.
