Watching a multi-channel site versus this one, not seeing any difference on DSD+ datastream.
What would I be looking for?

You might have to run more verbose logging to see it, and you would see it in the DOS screen.

Notice the "CompCC" -- for Composite Control Channel. If you see CompCC, you know that the control channel can serve voice too, and if you see voice on a CC you'll likely see DSDPlus display IDAS during the voice call.
UPDATE: Actually, CompCC will reveal that the CC is set up to handle voice if needed, but that doesn't guarantee a single channel site. In my area, starting out the regional NXDN system of one provider had only a single channel active per site. Now those same sites have multiple channels, yet the control channel still reports CompCC. So I'm not sure that CompCC present in the advertisements by the system is indicative of a single-channel site, but rather just indicates that the CC will perform double duty as a voice channel if the need arises. Somebody who knows more than I will have to verify that.
