Torger, on the left & right images, do you have the 'Simulate paper/ink' (ie. make my image look like crap) button on or off?
LittleCMS tifficc is used for soft-proofing here. I haven't written down which command I used for those images but it's likely:
tifficc -v -w16 -t1 -b -e -i printer.icc -o*sRGB print.tif proof.tif
This command is not simulating the paper or paper white as that is not producing a good perceptual match. For semi-glossy papers and the screen set to 6500k and viewing lamp at 5000k the similarity between screen and paper is very good. It's a bit more tricky to soft-proof matte papers due to the brighter blackpoint.
I know some run the screen at 5000k too as it's "mathematically correct", but that's a mistake as the eye doesn't make a full chromatic adaptation to a screen, probably due to the spiky spectra. That's why 6500k on screen (usually) matches quite well with 5000k on paper. People need to believe their eyes rather than instruments when it comes to screen/paper whitepoint matching.

A few thoughts on this:
- Targetting to sRGB will limit the proofing of highly saturated cyans and greens. It's a good option if you don't have a wide gamut monitor.
- If you drop the "-b" flag it should soft proof matte papers better.
- It normalizes the image output to the paper's white point so you may see some variation depending on the amount of OBAs in the paper.
