There could be a rare, rare case of someone with XXY chromosomes also getting it, but that would be two very rare human conditions hitting at once.

XXY males are around 0.2% of males, so about 7 million people, and tetrachromacy is anywhere from 15 to 50% of women, so we would expect 1 to 4 million tetrachromat males

The 15-50% is apprently women who have some sensitivity to different color bands, but not a full terrachromacy. That condition has only been identified once. Id expect for men with XXY chromosomes, for it to still be stunningly rare, if even present at all.
Its fully possible that the above sum is the number of men with some enhanced color depth, but even then in a population of 4 billion, 1-4 million is a very small number.

I have this, I am pretty sure. I had a job reviewing aerial imagery and in my first week I found camera defects in some new imagery we got in, that apparently no one else saw for years. It was extremely obvious to me. Needless to say, they kept me and put me on the experimental team. 😅
