The beauty of grain in 35mm was emphasized by long-lost 2475 Recording
Film, which could be hyper-sharp (not similar to "high resolution")
when its grain was left intact, rather than dissolved. Many of us used
DK50 and rated it at relatively slow 800 rather than the easily
achieved 3200 for exactly that grain reason, AND to enjoy the
incredibly long tonal scale. 

Incidentally, there IS no such thing as "underlying image information"
when it's not in the film. Loss of potential detail (eg through
today's reliance on zoom lenses)is directly comparable to abandonment
of potential tones through use of short scale films (such as Velvia).
