There is another difference. Gloating usually has to do with personal achievements or a victory won, or an enemy's downfall, that is, objectively real things or outcomes. But the practice in question is more superciliousness, a revelling in (supposedly) superior knowlege, so the combination of smug with pontificate is most apt. The only other neologism I could suggest would be to verbify supercilious - what would that be, to supercile?
