They look like the same deer to me coloring means nothing when finding sheds as one may have dropped a week or 2 earlier, or one may have been faced down and the other faced up and sun light all are factors. The number of points on each one doesn't matter that much either. Most deer never have that perfect set of matched antlers. There is always most something that is a little different about them.
I am not talking about the number of points but rather the frame size of each shed. I have found quite a few sheds in my day and in my experiences I would not think those two were shed in the same year.
Just my opinion.
