I'm not sure what you mean. The brightness of 120 was unattainable given the white point target, so it was automatically reduced. > Also the WP is quite far from D65. Seem pretty good to me given instrument and display drift: White Visual Daylight Temperature = 6291K, DE 2K to locus = 2.3 > Maybe you'll fine other strange values I cannot understand. No, it all looks pretty reasonable. I'm not clear what problems you are seeing. Graeme Gill.
