While I can't definitely confirm that it is not possible to check if
specific service is connected because I'm not a developer in this
project, I would say that this note from Device1.DisconnectProfile() API
docs suggests it:

Also, in case you haven't already seen it, I think you might find
interesting a part of the discussion of this patchset from some time ago
(regarding the need to show in UI which services are connected):

Hope this helps,
