Oh: Calibration hardware and EIZO !

Can ArgyllCMS by any chance access the built-in color sensor of the
EIZO CG displays?

Does anybody know that calibration hardware?
I guess it's tweaked for the CG (may be on physical filer level) but
is that small thing accurate enough to measure the dark patches or do
EIZO „cheat” and use „presets” for near-black according to the target
gamma? Or do they assume almost everybody will attack the display with
an external sensor and that's just a dummy?
