Digital BW, The Print

Terry, I found the Selenium MPS set plus GO produced a very different hue on the photo surfaces than matte. I'm not sure of other inksets in that regard. On matte, it's the familiar subtle neutral purpley look many of us have seen over the years. On the photo surfaces, it goes much warmer as you have observed, more to a rosey hue. In fact, as you note with the Harman, I found myself gravitating to the OBA papers for that ink as it knocked back that red a bit. Others on this list that got my samples may recall that.
I also have prints made by Jon for me of the new Warm K7 set, also glossy compatable with GO, and again the photo surface papers are much warmer than the matte prints.
It seems consistent across the board, the inkjet photo surfaces give different (warmer) prints than matte coatings with the identical Cone inks. It would be interesting to hear from others here about other mono matte/gloss inks.
Without having them right in front of me, I think the examples of both gloss and matte on various papers with the HP that John Dean sent me, they seem more consistant across different coatings.
