SOLVED!
So after scanning that page code again I noted nothing in the "game info" part of the page has any data in that page but there is a "GameDetailsView" binding reference right where I would expect that block to show so following my intuition I followed this to the GameDetailsView.xaml and now it is making far more sense, I see the value: PlatformClearLogoImagePath
So it's just a case of finding the linked files which now makes much more sense.
