Thank you so much!!! It worked!Well, I had one more thought and it worked. If anyone else has this problem, mine was solved by finding the Canon driver set for the PIXMA Pro9000 in Windows 8.1 (x64) environment. The driver is version 2.23 named: pro9000vst64223ej.exe and can be found here: www.usa.canon.com/cusa/support/consumer/printers_multifunction/pixma_pro_series/pixma_pro9000#DriversAndSoftware
Be sure to turn the printer off before installation; when the printer is turned back on again the new driver set will first uninstall whatever is residual from the WIN 10 installation and then install the new set. WIN 8.1 is not WIN 10 but it seems to work fine. I have been running print tests for the past hour and can confirm that the lost ICC codes are now returned and the print colors are correct.
