Apparently Qobuz with it’s native app is also not gapless but when integrated with various players it is.
I have absolutely no way of knowing whether a roon integration could accomplish the same but that is the point of the OP.
The lack of gapless and technical integration in general is disappointing for sure. The lack of anything above redbook I personally have no interest in. But on the other hand I find roon metadata, search, radio and discovery equally disappointing.
