Interesting accusation. What attributes of this photo would lend itself to be of better quality in such a display?

(Disclaimer: I think this display is awesome -- can't allocate the funds for it right now, but will be keeping an eye on it going forward.)

The image is "contrasty", showing lots of hard transitions from bright to dark. With displays of low bit-depth, the hard thing to do is smooth gradients of tonality.
