I don't think that AT even comes into play as high contrast mode is handled by the OS. High contrast mode is not the same as choosing a monochrome display. On Windows, the default high contrast display is mostly white on black, but there are still colors, and text is larger. On OS X, high contrast mode is just extremely contrasty with lots of detail getting washed out; you can separately choose to use grayscale and/or invert colors. Authors may want to provide images with lots of detail, but fall back to images with less detail and/or larger objects/text in the case of high contrast mode.
