talk to editors at busy post houses in LA (this is what they told me)...the small cost of post work on film shoots is saving a lot of money for producers..
I've heard this, too, but the cost is from conforming footage shot on multiple formats from multiple cameras and in multiple locations, edited by multiple editors, etc. not so much the cost saved because film has a nicer look "baked in."
There might be some truth to this on productions over the $100+ million mark shooting on multiple systems because cutting edge digital workflows are still being developed, or (I hate to say it here) with houses that have to deal with how finicky red footage/other raw formats can be for a house inexperienced in working with it, but it has no application for smaller projects.
Furthermore the (enormous) cost of a best light scan must be weighed against any additional work digital footage requires on a smaller scale project.
