I think that's an interesting detail in the artwork.  Seems detailed enough that it is (or was) a planned feature of the area.  I searched this morning for that HBP footage you referred to.  This is a portion of a screen shot (I tired to lighten it up for clarity) showing the tall front of Burgin and Burkes, just after Draco enters through a door below that tall window.
I think it would be a stretch to say there's a resemblence here.  But that certainly doesn't mean that the artist wasn't trying to depict Kockturn Alley or even Borgin and Burkes.
