The point has never been about the actual pixel color codes. It’s about how human perception doesn’t follow those objective metrics.
Distilled down, we perceive color and brightness in comparison to the surrounding scene. The checker shadow illusion is a clear example of the same color looking different.
So the color perception on the dress depends on how the brain decides to color correct the white balance of the scene.
I find it easy to switch back and forth between the two color combinations: If I assume that the scene is in full sun, then the dress looks blue and black. If I assume that it’s in the shade, but with a brightly-lit background, then it looks white and gold.
