Well the benefit should be occasionally reduced time to process the OSPF topology for shortest path.

There's some OSPF command to check time spent actually processing OSPF for shortest path, so I guess you could compare "before" vs. "after".  Trying to predict improvement would be difficult.  Remember impact of any savings very much depends on what part of OSPF topology changed relative to the router doing the shortest path computation.
