Oh! I might've had my screen tilted differently to see white and gold!
I guess, it also depends on which type of screen you might have. The older TFT type, or IPS or AMOLED. I've tried viewing the gamma adjusted images on my IPS screen and they don't change at any angle. The problem of technology, that actually works.
I'm not sure whether people are screwing around (to me it's unmistakeable that the dress is the colors of the individual pixels--blue and black/dark gray) or if there's a genuine difference of perception going on. I would be interested to know exactly what kinds of traits other than a willingness to mess with people's heads might be involved in this. I know I have unusually fine perception of chroma (absolute pitch, perfect color vision, etc.) that might make me more sensitive to the actual colors of the dress.
EDIT: The mystery is exaggerated by the fact that people forget that color perception isn't triggered just by the photons that hit your eyes. It's triggered by processes inside your brain, processes that are sometimes not even initiated by light. And different people's brains obviously work differently. It's the same type of thing that is going on when one person likes the scent of a perfume while another wrinkles their nose at it. Just another form of people having different reactions to things.
