Here's an enlarged example of the greyscale test. The top image is 255+Full+Full+Dithering (dynamic range expanded). The bottom image is 255+Limited+Limited+Dithering (dynamic range untouched). Note that I've exaggerated the contrast to make the dithering more obvious. Dithering is clearly not doing anything in the bottom example, and I'm inclined to believe that is the intended behavior.
