I have not seen any R3000 ICC profiles for any of the epson canvas rolls. I have a Colormunki which I presume can make an adequate profile as well.
We are working on R3000 profiles for the Exhibition Canvas products. I'll let all know when they are on the web site.
In the interim, you can certainly use the ColorMunki to generate your own profiles.
