I have a Sony X850C which supports HDR and it really has to be seen in person to be appreciated! As an Amazon Prime member, I get a fair bit of 4K HDR content and having a set like the Sony with a wider color gamut (both DCI and BT-2020, though the latter only has around 70% coverage), you will have so much perma-grin your face will hurt!

"Ultra HD Premium"

Unfortunately the requirements to "earn" this label on a TV have high standards for input (BT.2020 color space) but very very very low standards for display - only 90% DCI P3 is required. Which basically amounts to the exact same color space Rec.709 for HDTV specified. So that label on a 4K TV doesn't indicate anything like 'premium' and you'll be left to your own devices to figure out how wide the color gamut of the TV really is. HDR without a wider color gamut is pretty pointless after all!

 

Of course no TV ever made can display all of BT.2020's gamut, but that's fine. They should have at least required 100% of P3 since that's the current standard Hollywood has been used for digital projectors, so you could at least get the same color gamut you see at the theatre, and the "premium" label might mean a little something.

 

Oh well, what do you expect when CE companies developed the standard. Of course they wanted it easy to meet, so they can sell us cheap TVs that have more pixels but don't deliver anything else.

Does anyone already own 4K TV?

I was actually pretty amazed at CES to see the differences with pix -- with and without HDR (regardless the HDR format). Talk about visibly recognizable differeces.
