Yes.

If I use the matte black cartridge on EAM paper i get I brownish cast 
on the print using black only, but I can tell it's onsly using one 
cartridge by the coarse dots in this mode so I think that's just how 
this ink looks.

With photo black on Premium Semigloss I get a strong purple cast 
regardless of what I select in the driver, selecting 'Black' doesn't 
seem to have any effect at all as it still uses all available colors 
to create grays.
