Not at present. I don't have access to any displays with downloadable
video Luts, and certainly don't have an EIZO.

It's hard to know what they do. I saw the EIZO calibration
demo'd at one point, and by the speed and lack of test patches
I assume they are using a model of the display behaviour.

By contrast dispcal assumes very little about the display behaviour,
except that it is roughly additive.
