Does this page
http://www.kodak.com/country/US/en/motion/support/h1/exposureP.shtml help
(starting about half-way down the page, some images of grain, including a
SEM image)?

I rather like Reichmann's explanation, but I was surprised when I passed it
on to a friend who asked whether he had ever looked through a grain
magnifier. He said that grain is all shades of gray. My darkroom work was
only for a few months, in spare time, many years ago, but I have no memory
of either black or white for film grain although the focusing magnifier
probably did not produce an image of the actual grain.

The only thing I could find on the web was a brief explanation which showed
an illustration of a huge film grain crystal with a single molecule making
up the structure of the crystal being changed by a photon. That would seem
to indicate that a grain crystal could be any level of gray depending on how
many molecules were transformed by light.  Reichmann's argument depends
completely on the on-off digital state of a grain crystal. Does anyone know
the answer?

A side note is that while I was googling for an explanation I was amazed how
commercial enterprise seems to have pushed internet information way into the
background.
