We have a very "fuzzy" visual perception. I remember seeing an RGB response curve of the human vision mechanism once. I doubt it was measured. Maybe they extracted it from the CIELab stuff.

Anyway, things like the green (or blue -can't remember) receptor have a strong curve in the green spectrum, but also a "bump," over in red (I think).

We're an organic mess.

Looking at RGB curves for LEDs, they are three perfect little mountains. No "bumps," anywhere.

I guess that the goal is to try to mimic the "messy" human visual perception.

Also, expect these monitors to be non-cheap. Companies like Eizo are having a difficult time, justifying their prices, these days.
