Then your concept of visible metamerism is quite different than mine, as I 
have a wide collection of grayscale inkset prints, AWB prints, and neutral color 
mode prints, and a lightbooth with several lightsources... the only real 
difference I see in any of these with "two gray" printers (as opposed to the clear 
difference that shows with older printer models) is that the UV lightsource 
changes whitened papers in all cases; UV aside, they are all about as neutral 
under one source as under another, be it warm incandescent, 5000k, 6500k, or 
cool blue.
