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 XXY males

The 15-50% is apprently women who have some sensitivity to different color bands, but not full terrachromacy. That condition has only been identified once according to wikipedia. Id expect in 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, passed through dozens of eyes. It was extremely obvious to me. Needless to say, they kept me and put me on the experimental team. 😅 I have always been really good with colours.
