Hi ArtDen,
Your guideline to calculate color profile tells to set WB to daylight. I have pointed out in another thread that the daylight
is not actually a preset, and it can vary wildly if one points the camera to the CRT/LCD monitor (for calibration),depending on their color temp. (It is actually mixture of AWB and preset) See
Beware, WB presets don't have a fixed behaviour
My suggestion is to reset all camera settings to factory defaults, and then use the factory set custom white balance to find the color matrix, as it is the true preset and is close to daylight.
