That comment was a joke, I thought.

I'd love to see a graphic which shows you how far "out of tune" the guitar fretboard is
I don't think the graphics would be hard to do. The problem is defining what "out of tune" means. What is the reference?
I believe there is such a thing as perfect tuning for any given note but I do not think it is traditional just intonation and nobody thinks it is a tempered tuning system (nobody who thinks there is such a thing as perfect tuning, that is).
Some violinists will play scales in a different intonation than arpeggios - or at least the thirds of arpeggios. I think that is the right approach, but it makes it much more complicated to figure out what the reference pitch is.
I think there is a table on Wikipedia comparing ET to a system of just intonation, which does give some guide even if (as I believe) traditional just intonation is not really the right comparator.
I find this stuff interesting, but at the same time the ear has some tolerance and we get to a point where we are obsessing over stuff that doesn't really matter.
