Janos,

 

Absolute Colorimetric intent is *always* your friend ;-)

I don't know what was the problem but I created a new profile from the same
ti3 file and now it works like charm.

 

New white rectangle in paint, rendered without CMS -> ~5900K

Paint saved white rectangle in Photoshop, Relative colorimetric rendering ->
~6500K

New white rectangle in photoshop, Relative colorimetric rendering -> ~6500K

Photoshop saved white rectangle, rendered without CMS -> ~5900K

Photoshop saved and converted white rectangle, rendered without CMS ->
~6500K

Photoshop saved and converted white rectangle, Relative colorimetric
rendering-> ~6500K

 

 

If the Relative colorimetric intent is not my fiend then there is a problem
now. :)

 

 

Could it be a problem that I chose the Ultra quality mode for colorprof? (I
created a Low quality profile this time for a quick test.)

Could there be a limitation that some softwares can't work with ICC files
which has big file sizes and/or big LUT size?

 

But before somebody would open the champaign for me...

The gray gradient is a complete mess with this small cLUT profile. And
absolute colorimetric is still broken in MPC-HC (it is worse than the
current, small LUT based Relative colorimetric).
