That looks like some auto level thing like C.A.T.S - is that turned on on the
Panny for that input?

Unlike Windows I don't think OSS Radeon will do anything other than full range
RGB over HDMI - I would investigate the "dark" issue as perhaps setting XBMC
not to scale to full range may be confusing something that's trying to
automagically tweak things for you - Denon or TV - I don't know, but it's
normal for 16 - 235 luma to have samples that are below/above which usually get
corrected by the stretch to full range.

PS How did you add dither to xrandr?
