I guess that is if you leave Delta 100 out and RPX 100 (or whatever Rollei / agfa is called now).
I am sorry to say, that is just not true.
For reference, i once had the chance to work on a "mural" size print from a negative of a great image. the image was so amazing (as was the print, i did not make), we hung it at the front of the shop behind the main counter. I cannot even remember how many times people walked buy an said, wow, it must have been a challenge to carry an 8X10 up that mountain, in south east asia, or what kind of lens was that shot with?, or i am sure that was some tech pan. The truth was that it was HP5+, 35mm, shot with a canon plastic 50mm 1.8. That print was 1X1.5 meters. I am sure others can attest to that capability.
Allowed/acceptable circles of confusion are all that matters in really large size prints. The LPM resolution of a film could not possible affect the visible resolution of a print, at any size, to a naked eye, not to mention, the resolution of the paper is the limiting factor here. If one takes a loupe to a mural size print, well, someone else can complete that sentence.
