Thanks for clarifying David. You've been extremely helpful regarding this issue...
As far as your earlier response, are you suggesting that the CMunki and the Spder3 both build profiles that are surprisingly similar to one another (insofar as they apply to Eizo WG monitors)? Or are you saying that one builds a better profile than the other (for Eizo WG monitors)? Sorry, I obviously have trouble with reading and English :)

Instead of using a CIE Observer based on a 2 degree field of view (reading vision) they use the one based on 10 degree (broader field of vision). ICC is based on 2 degree; big, flat colored objects (textiles, car paint) use 10 degree. Its just a different standard for replicating a different component of human vision. Since a flat gray 22 inch screen is a large object, they are looking at using that matching function. It has nothing to do with the devices they are measuring with.
