1. What you're describing simply ain't metamerism: it's a fact of the physics of light that all prints will look different in different light as the light itself -- tungsten, neon, daylight, etc -- imparts colors to the print it illuminates. Thus, a perfectly neutral print will appear to be different in tone under different types of light. Metamerism is the pheneomenon that a particular tone within a neutral print will look different from the rest of the tones in the print: a "color cross-over" in plain English.

2. Also, I have made extensive tests and do not beleive that the 1280, even with the best profile, can print "dead on neutral", as you state. There is always a color cast in some of the tones (but, again, that is not metamerism).
