It is probably just the lightning. You can tell the models are identical. It's just different colours/shades. I wouldn't quit that easily. There might be settings to shade them back to their more original appearances.
It is not just the lighting, and the models are not identical. Close, sure, but subtle details have profound effects. If you look closely you can see places where the shape/sculpt of various features have been visibly changed.
