>>I have always been under the impression that it was the pigment inks that were prone to meteramism. Some papers were worse than others and Epson did produce several versions of their 2000P driver to try and combat the problem.

Epson was fresh from their catastrophe with the ozone fading in the dye-ink 1270 when they released the pigment-ink 2000 only to find they had a new crisis: massive color inconstancy (what you call metamerism).  Ironically, the "fix" they found for the 1270 was to offer an encapsulating paper coating which eliminated the ozone fading, but introduced color inconstancy. So "metamerism", as you call it is not solely a pigment problem; encapsulated pigments, or dye encapsulating paper coatings for dyes can cause it in either colorant type. 

>>I did not think the carbon inksets were prone to meteramism, or not as badly as the pigment colour inks.

Near-neutral inks, such as carbons, are not prone to any significant degree of color shifting.
