It does not manually profile well with the Epson driver.  The LLK and LK
interfere too much.  PFP (for neutral) and QTR will be fine with it.

I found just replacing the yellow with a gray ink (MIS EZ-W, even chip
compatible [amazingly]) worked so well there was not much reason to do more,
but it will have the color dots under a loupe.  On the other hand, I doubt
there is any significant difference between color inks that are separate as
opposed to those that are mixed into the inks.  The difference in my fade
tests was so little that is was probably below the expected noise level --
i.e., not significant.

>and maybe an eboni version 

No, at least I've recommended they not try that.  The multi-channel Eboni
needs 1.5 pl dots to work at what I consider "photo quality."  The k3
printers use large dots.
