Andy: I also know of at least one profiling applicaion that includes a “flavor” of perceptual rendering for device links that does a very deft job of scaling values close to the white point. I was referring to perceptual tables built into most ouput profiles. These might not always produce a convincing result. In any event, what is clear is that Fogra is not to blame for the paper color, and thus for the characterization.

Rendering neutrals from ab=0,0 to ab=2,5 -10 is quite a change and XYZ-scaling from black to white does not reflect the required XYZ to be printed to actually get a decent print. The solution would be to use a perceptual rendering intent that does a grey mapping close to ab=0,0 and not to what XYZ scaling predicts. I know many color server device link profiles (F39 - F52 and also ECI-RGB to F52) that does this job. regards Andy Kraushaar PS: So please believe me that the people that doing this huge (unpaid) efforts also do check the separation, yes!
