Ron-

The two reasons for this are the absolute color reference and the
precompression of the tonal range (into something more akin to what
book/magazine/newspaper printing can handle) which reversal film
provides.

I don't know what you mean by "accurate," but color negative film can
record a far greater (up to 6 stops greater) range of contrast than
reversal film. The difficulty is then finding a medium which will
support this dynamic range in viewable positive form... paper prints
don't even come close, and if you're going to wind up with a film
positive you may as well for all intents and purposes start with one!
