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.
