There's always an RPF check. You want to look at the failures! :)
But otherwise, yes, the check is made based on your routing table entries.
So whatever protocol/method you are using to route traffic back to the
source of the multicast, that is what's being looked at for the Multicast
RPF check.
HTH,

It doesn't matter how your routing table is populated, IGP or static routes.
If the traffic is received on an interface that is not the rpf interface you
need the static mroute. Like Cyrus said you can use debug commands to see if
there is an rpf check.
