You don't seem to understand the bare minimum concept here. You percieve smooth transitional colors on a spectrum, mantis shrimp would see slices of colors they can recognize and large regions inbetween.
The physical eyes themselves might be perfectly capable of it, but they dont have the processing power to recognize the inputs.
The reason for their adaptation is not to improve color vision, but to percieve depth better for punching with.
Can they not see the strength of colors, only their presence? Or can they not see different colors in the same location?
Is it just that they can see the color channels separately but not combine them?
Imagine if everything you saw was one of a selection of colors. All blues are just Navy Blue. All reds and oranges are just red. They cannot tell them apart.
So it cannot tell the difference between different receptor strengths, such as bright blue vs dark blue, each only has a presence and an absence, like a 1-bit per channel quantized image?
Surely it could also see blue in the same place as it sees red, and then gain information from that even if it does not interpret that as purple?
If both of these were true than it would be able to see 2^12=4096 distinct 'colors' (where each is a combination of wavelengths originating from the same area)
