Digital BW, The Print

I see this repeated all the time, but I really wonder whether it's
true... The Epson driver also uses a very large amount of cyan and
magenta to produce BW, and those inks clearly display strong metamerism
on color pictures - A have a picture with a deep blue sky in front of me
now, and under the fluorescent light on my desk it's very purple, while
under a normal lightbulb it's much closer to cyan - Big difference. This
reflects the metamerism I see in BW pictures printed with the Epson
driver.
