Canson Baryta Matt

As per a previous discussion with this paper, I asked if there was a Piezography Pro curve for this. There was no reply, so I decided to run three prints of test targets, 100% cool, 100% neutral, & 100% warm. The Media setting for the Paper as recommended by Canson was set to Ultra Premium Matt on the printer, a P800.
The 1st print I made (100%cool) I forgot to change from PK to MK in the QTRgui (windows) but used the curve for P800 Canson-BarytaPhoto-Cool. Since there is no BarytaMatt curve available.
Since I forgot to change the ink selection in QTRgui to matt and it used a “PHOTO” curve, I was surprised to see that no GO overprinted the page which I somewhat expected to see since I used a Photo (indicating PK ink) curve and the PK ink was selected in QTRgui. does this indicate that the GO is selected by the media selected and not the curve or ink selection?
