Funnily enough there's actually sexual dimorphism in human vision. While studies about exactly how different the structure of the eye is and how it might differ from an assumed objective commonalities is still not conclusive it's thought Female phenotypic people supposedly do tend to have higher color differentiation on average and are better at recognition of static objects while Male phenotypic people have better night vision and ability to interpret objects in motion.

So a guy holding up two paint swatches they can't tell the difference in and being confused is basically a cross cultural phenomenon.

Yeah but printers are optimized for trichromats and these color swatches are printed, so they should look the same to a tetrachromat as everyone else.

Which gives makes me feel bad for them cause all printed media, and any TV, monitor, or phone display that can't do 1000+ nit HDR must look very dull and unrealistic to a tetrachromat. Hell, even HDR 400 (the minimum standard) in of itself is still a relatively niche feature, let alone HDR 1000+.

Women are more likely to have more rods and cones in their eyes and are therefore more likely to be able to identify the difference between very similar shades and hues as well.

I can see the difference just fine; I'm male.

Makes sense.
