Thing is that catalogue image is so /obviously/ Black & Blue. Like the photo taken has to have been one of the worst photos in history to somehow lose all that colour information.

The pic lost no information (my friend checked the RGB value and confirmed it was indeed blue) and "having a shit screen" has nothing to do with it. It's something about how the cones in your eyes react to the way the light hits the dress.

It is a terrible picture (yes the pixels are blue but not nearly as blue as the actual dress), but yeah really the issue is with how your brain makes a guess at the lighting and then subtracts that assumed lighting from the image to give you the "true" color.
