I have recently converted our 9900 to run a set of K7 neutral inks, both matte and gloss. The black channel in the printer is permanently clogged so I have loaded the new Ultra HD Matte black in the orange slot and the new High Density Photo Black into green, I have Piezoflush in the MK and PK cartridges. I am using ErgoSoft V15 to run the printer and create our own setups for each paper.
Basically my issue is that prints are too yellow in the lighter tones, slightly blue in the darker tones but then a nice neutral black. This is happening on different papers, Hahnemuhle Photo Rag, Hahnemuhle German Etching, Canson Rag Photographique, Ilford Textured Cotton Rag and Ilford Cotton Artist Textured are what I have tried.
I have printed the 10 ink purge image from QTR in calibration mode with ink calibration on 100, 2880 dpi and unidirectional, I cropped it to save paper. I have attached a photo of it, it’s just a snap from my phone sorry. I printed it on Ilford Cotton Artist Textured, a warm paper with no OBAs. I scanned each patch in i1Profiler to check I’m not going crazy, these are the results. I get the same sort of results on all matte papers that I have tried. I haven’t made it to gloss properly yet.

When I set up the printer I did an initial fill with Piezoflush and let it sit for 48 hours, and then filled with the K7 inks and did an initial fill. I have since done another two initial fills with the inks after agitating the cartridges just to make sure there’s no settling. I have also cleaned the capping station.
Any suggestions are most appreciated.
