As far as I know there is absolutely nothing you can do to colour manage 
web graphics. 

Certainly there is no evidence that web browsers take any notice of 
embedded colour spaces, and if they did there's no point in doing so as 
user monitors are going to be about .001% calibrated and the rest 
uncalibrated!
