Yes, I used a shaper matrix.

No, nothing changed...

This is strange, because I can see a vcgt tag in the profile. It looks like
it used the LUT installed in my video card... Well, I think it is not
really a problem, as it can't modify the photo frame LUT.
But the tone curves are rally hugly :o( I also think I'm too far from a
calibrated screen to do a correct job... I can play with the
luminosity/contrast knobs, but is there a way to do that with the help of
the instrument, or just with a special set of patches (and my eyes)? It is
hard to figure out where are the best values...
