The key is what paper type Epson used when creating the profiles . . .
When I downloaded the Legacy Profiles installation file from the Epson support web site for my P9000, I'm pretty sure it contained PDFs for each of the profiles indicating all the important parameters used when the profiles were created. In any case, I have the PDFs here and listed below are some of the parameters as shown in these documents:
