Are there decided recent games with 1. b4 at top level? I would like to have a survey of the decided games with 1.b4 since 2010,
 where both players had at least 2600 Elo. 

chessgames.com allows to search games with given moves (with tight limits), but 
 does not allow to search for Elo.

Can anyone help ?
The only games I could find meeting your criteria are


Ivanchuk - Giri, Leon Masters (rapid) 2013
Short - Caruana, London Classic (rapid) 2013
