This is different than how previous samsung CMS's have behaved in which everything was oversaturated including gamma target values of 2.4. So there is no headroom to desaturate the pseudo-primaries in the 75%/75% colorspace. This can be counteracted by raising the color control. I found that color=55 was a good fit for an effective BT.1886 2.4 target.
haha, too funny that you just made this post...
I just put together a new HTPC, and spent most of the day today messing with calibration again. the last I'd done, I used my ps3 so I was trying to adjust things using the pc controls only. there were a few issues with that, that aren't really worth getting into, and one of the things I was forced to change was using RGB output, and having it set to limited. with full, there was no setting for brightness that would not show dithering in 'black'.
anyway, I started off the afternoon trying to get things to work with color at 50, and 2hrs later said f-it, I'm going back to the increased color setting. by that time, I was a bit too annoyed with everything to run numerous sweeps and figure out what the 'best' setting for color was, so I think I just set it to 60 and went from there. I didn't manage all my dE's under 3, but I definitely had better results with my old PC.
but now that I'm sitting here, it's nice to know that this isn't a compromise I'm making to use my HTPC, it's just the way the tv needs to be for a certain gamma. my priority right now though is to get the projector dialed in with the new HTPC. once that's done, I might re-visit the f8500
