Do not have a DP but I believe the back end is basically Hopper, so suspect it would be treated the same as a booking made through Hopper which I do not think earn EQN
Of all the CC travel portals, I think Amex is the only one that gets you elite recognition
I don't need the EQN for this year (at 70 nights YTD and 80 is not going to happen) or really the comp breakfast, but the points would be nice. I booked the HR Vancouver via C1...will report back.
