Now it gets complicated...Thanks for the education.Do these clear / non-pigmented inks counter gloss differential by making high value areas as shiny as low values or do they reduce gloss toward the paper's natural low level, i.e. dull everything? Using my P600, even areas close to paper white are shiny with Hahnemuhle FineArt Baryta Satin.
Canon and Epson claim they are doing different things, even that they are solving different problems. I think the end result is the same - that of improvement of the reflective quality in some way.
If I understand correctly, Epson works by filling in the sparsely color-coated areas, both at micro and macro level, with clear droplets. The resin has higher gloss than a typical satin or glossy paper so the effect would be to make the high value (low ink) areas as shiny as the low value (high ink) areas, i.e. equalizing up, not down. I have a P400 (since about 2 weeks) and I can notice higher gloss (compared to the rest of the paper) in the white border around an image, for example. It can be seen very clearly at an angle, but not straight on. I am still learning how to use this judiciously with different modes (on, auto, off) that are available. I am not sure if your displeasure with the satin paper is simply that it is too shiny to start with or that you are indeed perceiving the distraction of the gloss differential on P600. Or may be it is both.
Canon apparently applies a blanket coating in the inked areas, the liquid leveling off over the height of the pigment particles as nicely explained here:

I am not sure what the formulation of their clear ink is but my guess is it is not the same as the encapsulant. The question is whether it cuts down on the overall gloss or increases it. I personally have no experience with Canon printers. The illustrations in the link seem to suggest that that it lowers the amount of reflections in the dense areas like shadows whereas increases it in the highlights.
In a way the Canon approach seems to be akin to the silver gelatin papers where the silver particles are embedded in a matrix of gelatin. It would be interesting to take a satin print from P600 (or even a matte print) and run it through Pro-1000 with a blank image to make it coat the Chroma Optimizer and see what it does.
