cannot manage LUT-based-profiles very well. The profile, generated with the default settings of discalGui, made a matrix with R and G swapped. That was the reason for the wrong colors.
Right. It's a dummy table to indicate that the matrix is being used rather than the intended cLut, while satisfying the ICC specifications.
By the way: In my eyes, this settng as default in dispcalgui is a little bit unhappy for a normal user, who only wants to build a running icc-profile (Sorry Florian)
You have the choice of building a matrix profile if you want, and then you know that you are using a matrix. Graeme Gill.
