When i turned the picture upside down with the light source in the back now at the bottom, which couldn't be the sun anymore, my perceived color changed from very very light blue to blue instantly. And now I can't unsee it:)
People are not correcting blue to white. The image is measurably white and not blue. Some people may be correcting back to blue but regardless of whether or not the original dress is blue there is no deep blue of the original dress in the image being displayed. We can measure the RGB or HSV or whatever of every pixel and see that objectively
