Since you say FIB, yes.  If all RIB prefixes and their sub-prefixes go the same next-hop, then you don't need to install additional entries in the FIB.  Some platforms only can install ~8k/second.  Reducing duplicate entries is always helpful.

One can't do RIB compression due to the nature of the protocol.
