What Mark replied is correct, this is why I mentionned bluray 4K as well, to simplify, it doesn't need to be optical, what I mean by that is a standard for content improving on the 8 bits with half chroma (YCbCr420) of bluray.
The 12 bits of your Oppo is a nice marketting trick. What "deepcolor" does for bluray is get the player upscale the color depth, through interpolation, which is what the display would do internally if sent the untouched bluray content. It's simply a joke, but it makes customers happy.
It's exactly like the new sony bluray player upscaling to 4K. A joke. Upscaled 1080p cannot be used without a 4K display, and any 4K display on the market is bound to have a better upscaler than the player, or at least you would hope so given the price difference. The VW1000, for example, definitely does. So having the upscaler in the player doesn't give you anything. Except that the upscaling takes place in the player, possibly - probably - giving you a worse picture than if you let the display do the upscaling. Plus of course when the new bluray 4K or HDMI standard is released, they won't be compatible.
So to clarify again, you need a few things to things to improve on bluray 1080p content:
- better color resolution than YCbCr420 as encoded in bluray. We're hoping for YCbCr422 at 10 or 12 bits. This would be part of a new 4K standard, whether it is based on an optical bluray (what I called bluray 4K) or another support (hdd, ssd, sd, download, etc). Because it means higher bitrate, it might also need the new HDMI standard to support this at high frame rates in 4K, unless the new content format is better compressed to fit on existing bluray discs, as in that case the content might fit throught HDMI 1.4 still compressed, and be decoded within the player (similar to HD Audio, DTSHD and Dolby TrueHD are sent compressed, while LPCM is decoded in the player and sent uncompressed, which requires more bandwidth). This (4K fitting on standard bluray) is unlikely to happen, but still a possibility I guess as red claims to be able to compress 4K within the same footprint as 1080p bluray. Also it would be a solution for 2D only, 3D 4K would definitely need the higher bandwidth of the new HDMI standard.
- better horizontal/vertical resolution in the content itself (no upscaling), which will need the new HDMI to deal with the increased bandwidth at rates higher than 24/30 fps in 2D and for 3D 4K, which isn't handled by the current HDMI at all
- so you will most likely need a source and a display updated to the new HDMI format to benefit from these improvements to the content format. Provided the new e-shift JVCs get the new HDMI, they should be able to support the increased color resolution fully, and the increased horizontal/vertical resolution partially (half of what a true 4K display could do, but twice what a non e-shift display would). Without 4K inputs, the new JVC would give you the same interpolated 4K lite with no color resolution increase and upscaled 1080p. They will not be able to display native 4K content at all. If Ron's timing for the new HDMI boards is right (and he is usually right), this is bad news for the fall 2013 generation.
- of course everything in the video path between the source and display need to be updated too, which means VP, darbee, AVR or you fall back to 1080p. The AVR is a special case as if you handle input switching through a VP (or a 4K switch with separate output for audio) you can get it out of the video path and not upgrade. Same thing if you use only one 4K source which has a separate HDMI out for audio. No improvement for audio are planned in the new 4K format or bluray 4K as far as I know, upgrading the AVR is only needed if you use it to switch at least one 4K source.
