This should probably be fixed to account for the scenario where an HDMI connector is plugged directly into the DP++ port. I don't think the dp.subconnector property will be valid in that case. (Unfortunately I don't remember how one detects that particular situation.)
One may or may not be able to detect it very well. I've seen dongles that automagically change the DFP type from DP++ to DP/HDMI depending on what's plugged in, and I've also seen dongles that leave the DFP type to DP++.
Well, our internal logic certainly knows if it's driving DP or TMDS. I just don't remember how it knows this.
