Dear Mr. Karp,
... but can not leave your statement uncommented. :-)
Well, I had the same thought when I read your email ;-)
>displays black-point will be lowest when all channels (in the monitor LUT) are at the minimum value for black. Then a specific color temperature is given. This is true for _all_ monitor manufacturers ;-)
Yes and No. EIZO compensates this by balancing all gray scales in a separate LUT (per each R,G and B).
Since very dark tones are too difficult to be measure with devices in the field (colorimeters & simple spectra photometers) EIZO does it with color analyzers in the factory.
The other LUT, facing to the users calibration, provides a balanced white/grey/black
It is complicated and to much for email discussions therefore we have issued a white paper.
It deals with model CG220, but chapter 3-1-2 is also valid for CG210.

>[1] It still puzzles me, why it should make a difference to calculate with 12, 14, 16, 20348 or whatever bit depth, ...
Again it is difficult to explain in very short. Sorry.
It is a matter of assigning signal input level to the correct output colour tone at the monitor. If you have 10 Bit you could only differentiate in 1024 steps. An accurate calibration of lower tones results in the need of having more steps, since target color tones are very close to each others. If you do those calculations with 256 steps or 1024 steps you simply can not address them precisely. Please check out figures 11 to 14 of a.m. white paper.
With best regards / Mit freundlichen Grüßen
