I get blue bars with 3DLUT that exceed step 235 (monvo already posted this problem).
Something is wrong.
It appears that when using anything else as an .icm reference than what came in the "ref" directory, will make the scale blue.
Using Measured.icm as reference make it blue.
Using Rec709, Rec709_Gamma22 everything OK.
Removing the -G command makes it even bluer !!
Again, something is wrong with the color space conversion.
-ia makes rec709 and Rec709_Gamma22 BLUE !!!
Maybe the scale is blue because the monitor has a wider gamut in the blues and somewhere the color space conversion goes wrong?
P.S. I did not calibrate to K65, I calibrated to Native (measured).
It would be very nice if we could only take the color space form the reference Rec709.icm file (without the embedded Gamma), and take the Gamma from the Measured.icm.
Do you use latest version (32-bit)?
What type of profile do you use (LUT, Curves)?
Try profiling with Curves+Matrix (128 grey, 40 Single, 0 Iterative).
