I've seen it as both. I feel like I'm in a special club.
Nah that's quite normal, as far as I understand it.
With very sensitive cones in your eyes, you can always make out the actual blue (and therefore black).
With pretty un-sensitive cones, you'll basically never be able to see the blue because of the contrast/brightness levels of the photo, so it'll always come out white (and therefore the black looks gold).
But if you're in between, then it'll depend on the brightness/contrast of the screen, the brightness of the rest of the screen around the photo, etc. So if you're seeing it both at different times then you're somewhere in the middle in terms of having sensitive cones.
