The skill you are describing is usually called “absolute pitch”—someone without absolute pitch cannot easily tell the difference between A=440 and A=432 in isolation (to say nothing of something like A=442).

The notion of “out of tune” is different for people with and without absolute pitch. Someone with absolute pitch can hear something as “out of tune” just because it uses A=432 instead of A=440, whereas someone without absolute pitch will hear it as in tune. That is, more or less, THE characteristic difference between having absolute pitch and not having absolute pitch.
I don’t have absolute pitch. I’ll hear a guitar as out of tune if it is not tuned to itself. Like, if one string is flat relative to the others. However, if you tune a guitar to standard tuning in A=432, that sounds “in tune” to me. I think I have a decent sense of tuning—you can tune to equal temperament, and you can tune to just intonation, and I can tell the difference between the two. But I cannot tell the difference between A=440 and A=432.
The difference between 440 and 442 is exceptionally small, I’d be surprised if you could hear the difference in an A/B test.
