You selected the brightest highlights on the dress. I selected more average colors here.
I also included WHITE AND GOLD next to the selected colors, so you can see what they actually look like. Are you really saying that blue is white and brown-grey is gold?
You can sample the colours and see it’s white with a very light blue tinge and gold.
People who see it as blue and black are (correctly in this case) auto-correcting for the yellow light as the dress itself is black and blue.
Whereas people who see it as white and gold are (subconsciously) assuming a blue shadow and seeing the pixels as they’re displayed.

Well you would select the brightest bit to get an idea of the bit that was least impacted by the shadow.
But yes still closer to white and gold than (dark) blue and black
