Perhaps you're looking too much into it.
Sure there might be a bit more detail, but does that affect the overall outcome of the episode? For example if you're watching an episode of Heroes and they've changed Claire's hairstyle does that affect how well the episode comes out? Or if you're watching an episode of Back in the Barnyard and they've changed around Otis' spots, does that change how well the episode is made? It doesn't or at least it shouldn't unless it's supposed to be part of the plot.
