Audioquest Perfect Surface Metals

I can not find anything on the web that shows pictures (presumably under a microscope) that demonstrate the qualities/properties of AQ's much heralded PSC/PSC+/PSS metals.  It's hard to believe there are none.  Wouldn't AQ themselves put these up?  You can find the "single grain copper", OFC, etc. pictures, which have been around for a long time.  Before AQ went from "functionally perfect copper" to "long grain coper" (still available on their cheaper cables), they had a lot of back up for these metals (their website still does).  Then out came the three I mentioned above, and unless I am missing something it seems like we are supposed to take it on faith that these metals exist and are somehow different.  I also find it hard to believe that no one with a microscope has cut open some of these cables and posted something to the web.  I just must be missing it.  Is anyone aware of pictures or some other evidence that records the properties of these metals?  I notice that Cardas' website says they polish their copper after each annealing stage, and that good copper is so hard to find they had to make their own.  So where is AQ getting theirs from?   When one of their cables nearly doubles in price because it changes from LGC to PSC I would think there would be more support/evidence for this supposed improvement.  I own several AQ cables by the way.
