But xvYCC-encoded sources can be played on non-xvYCC hardware because xvYCC video's "core" or "root" video is a "nornal" HD video stream. Only the expanded gamut data is encoded separately from the conventional video stream... if that "extra" data is not there, xvYCC can't do anything. And if that "extra" data is there, the video will still play normally even if xvYCC is disabled... you just won't get the wider gamut. If you don't have a personal digital video camera that you use to make xvYCC-encoded video and nobody ever sends you such a disc, you'll NEVER use xvYCC whether it is enabled or disabled.
I know there's no recent activity here, but wanted to ask a question regarding this. I have a UN65ES8000 Sammy and a Pioneer Elite VSX-53 AVR. I know both support xvYCC, so thought I should turn it on in the TV menu. After reading this I figured there would be no change because the actual source from DirecTV isn't sending an actual xvYCC signal, or whatever you want to call it, but when I turn xvYCC on in the TV menu, I get a definite change in my picture quality. I'm not saying it looks better, but there is a definite and obvious change in the colors on the TV. They actually seem to look a little washed out compared to having it off, but still. So my question is, why am I able to see a change in my picture/color quality when enabling it if the source doesn't actually have it? Is it being added by the AVR and the TV is utilizing it from there? If that's the case, should it be left on for a wider color gamut and then recalibrated?
