Yeah, but the way their optical perception is wired, they still have worse color perception than humans. Basically, each cone (color sensor) a mantis shrimp has only sees a very narrow band of wavelengths. If a mantis shrimp has 15 cones, it can basically only see 15 specific colors. So while humans only have 3 cones, they overlap heavily and our brains can process the ratio of signals to mix colors.
