That would always constitute a failure, as a creepage failure is not a defined discharge as with clearance, but more a leakage current phenomena. If you fill up the gap with a conductive substance there *will* be a leakage current.

I don't see the point you are making. The whole idea is that the pollution becomes a conductive substance even if it didn't start as other than a rather poor insulator (there must be some initial current, even if it's picoamps).
