I was _not_ talking about the calibration accuracy in general. [1]
My statement was that a 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 ;-) When the user wants a different color temperature
the calibration has to increase one or two of the channnels to achieve
the target color temperature. Then the black-luminance is somewhat
higher of course. This is true for all displays also :-) A calibration
(calculation) accuracy of 12 or more bits doesn't influence this fact.
[1] It still puzzles me, why it should make a difference to calculate
with 12, 14, 16, 20348 or whatever bit depth, when the panel is driven
with 8 bits or with a "trick" with 10 bits via time-frame-modulation.
If I measure the perimeter of the earth with an accuracy in mm, but in
my table of perimeters of different planets I can only insert values
in m the table won't show me a higher accuracy when I measure the
perimeter with an accuracy in µm or nm... The same is true for
displays. It doesn't matter if I calculate with 12, 14 or higher bit
depth when my output is in 8 Bit (or at best in 10 Bits). A somewhat
higher bit depth (for example 12 bits for input/calculation, when
output is in 10 bits) makes sense, so that you will not loose levels
due rounding.
With kind regards
Peter Karp
