Thats the new DLC. It's supposed to look like that. And I don't think Steve Peat, or any world cup racer for that matter, would be running a leaky fork.
Steve Peat is a Blackbox Labs Factory rider. Its basically SRAM, Avid, Truvativ and Rock Shox's prototype testing sub-branch. For most of 2010 all the Blackbox riders were given a special upper tube coating on their Boxxer's. As far as I know only Marc Beaumont, Steve Peat, Brendan Fairclough, Sam Hill and Greg Minnaar are the only downhillers to have access to this but I'm not 100% sure
