Now that you mention that, it kinda does. I honestly don't know if thats what it is or not. When I bought it, they told me it was a bairds/corn hybrid...but I bought it purely based on the way it looks so I never thought much about it. But his greyish color is just the bad camera. In person he has more purple coloring to him which looks closer to the bairds rat than a ghost corn.
But it's possible im sure. He won't be breeding though, so I guess it's ok to be a mystery.
