If the calculation wasn't, as it seems to be:
BBC 1 vs ITV, ITV+1, ITV Player, Catch-up
but instead
BBC 1, BBC iPlayer, Catch-up vs ITV, ITV+1, ITV Player, Catch-up
...I suspect it wouldn't look too pretty for ITV. I'm also continuously sceptical about these additional viewer numbers apparently watching online. It's still a mystery why ITV isn't singing this massive flow of online traffic from the roof tops rather than letting spurious mentions leak out anonymously to the press. Something definitely doesn't sit right with that.
Not least because watching anything on ITV Player online is enough to make your eyes and ears bleed. Compared to the BBC iPlayer it's truly a terrible service with awful picture and awful sound quality.
