Being that it's in B&W and most of the stills I've seen from that scene are also B&W, I presumed it's also a still from the same photo B&W shoot. But who knows? Though, one might think a screen caps would be in color. I can't say I've ever seen someone greyscale a color screen cap just for the fun of it. But I suppose there's always a first time. Maybe someone wanted to be arty...
