Hi Tobias,
The concern is actually not that the blue cast exists. The concern is
that it changes from blue to purple by just enabling the "contrast
brightness saturation module" - without populating any values in it.
My expectation is that if I am to enable the module and do not modify
any of the values - brightness / contrast or saturation - all of them
remain zero - then it should not alter the image (but it does).
Regards,
B

The only difference between the 2 images is turning ON or OFF Contrast
Brightness Saturation. However - the values remain 0,0,0
I expect that there should be no change as even if the module is active
- I have not changed any values within it
Even the histogram changes by just enabling the module and the exported
images are certainly different.
Is this expected? I did not expect it.
What you are seeing is a problem with very saturated blue. Try enabling the
gamut clipping in the input color profile (2nd dropdown there). Set it to
"linear Rec2020 RGB" for a start.
DT 2.2.4 on Ubuntu 16.04.
