People view the image in different conditions. There’s so many factors involved. How bright your surroundings are, the make and size of your display device, how you perceive colors. Professionals perform color grading to avoid ambiguity like this in movies and such. Even your cultural expectations are hypothesized to change how you perceive the dress. (Eg. living in a desert environment can make you expect more yellow shading)
There’s a similar illusion called the spinning dancer, where some people simply cannot see the image spinning one way or the other, while some can even switch between them. There’s more information in the dress to make an objective assessment, but if that information isn’t observed or obscured by the aforementioned reasons, it’s totally understandable. That’s what OP’s image is showing.
