Unfortunately I don't. I wish I did though. I have tried some training, to no avail. When hear a pitch I have no notion of uniqueness.
However, since I listen to so much music and tune my violin to A 440Hz every time I play, my ear knows when something is off even by a degree or two when listening to some European orchestras. And I think every musician hates out of tune music :)
There is a really cool phenomenon with some musicians who play instruments with a one to one correspondence between a pitch and feeling + fingering (so woodwinds, and sort of brass) that have played long tones for so long that they have internalized the "feeling" of a note and can (with a small delay) seem like they have absolute pitch. Really cool stuff. A youtuber called Saxologic dubbed this ability "Real Pitch". Really interesting video showing this in action: https://www.youtube.com/watch?v=x4zo6POThHc
