I'd disagree, Vegeta's form does not appear to be Ultra Instinct, and the lead into the episode even called it "Vegeta's entirely different than Goku's power-up" or something of the sort. UI has been shown as normal black hair with a sheen to it combined with Silver-ish eyes. I'm with Raziere on this one, this more appears to be a different level to SSB, or Blue 2.
