Damn I really didn't want to jump into 4K yet but the value proposition of this is cray cray. Is this one of the TV sets that has low input lag?

Doh already bought the pro. The markup in Canada sucks anyway. Plus I rather wait until 65" with full HDR will be more affordable.

It's a decent tv, actual 10 bit panel, yet no wide color gamut and HDR only reaching half the brightness of the full spec. Good for gaming anyway with low input lag. 32ms with HDR. (Low for HDR gaming anyway)

Sort of going off topic.  My display is also a 10 bit panel but no wide color gamut if I understand correctly.  Is this a 'bad" thing, but it does product a very pretty picture.  Is there something I might be really missing out on.

I had my eye on X850D, I'll keep waiting.

Nonetheless, a pretty good deal.

I would have bought this if I hadn't already bought my current tv.

Now that's a deal

HDR was patched-in recently [on the X700D] via a firmware update, but it doesn't have Wide Color Gamut to take full advantage of it.

The X800D is a much better set all around.

10 bit ensures smoother gradients, less color banding.

Wide color gamut mainly produces better, richer greens, as you can see from the measurements below. Red gets a smaller boost, blue the smallest. Wide color gamut can produce more natural looking colors. The percentages are how much the tv covers of the rec.2020 color space (which in itself covers up to 70% of human color vision) To compare, the rec.709 standard for HDTV only covers 35% of human color vision.
Max 59% on the 700D might look bad on paper, yet it's still better at 1.18x the coverage of rec.709, while the B6 has a 1.48x increase over rec.709.
(Plus I doubt many older tvs actually reached the ful rec.709 spec, so the upgrade to rec.709 content will be visible too)

Current leader in wide color gamut, LG B6

After seeing this and how simple you explained it, it's starting to make a little more sense.  And just comparing numbers, here's mine:

Wide Color Gamut : No

I almost ran out the door to get this when I saw it but glad I held off. After reading reviews on that TV + watching reviews on youtube, it is NOT the best HDR TV by a long shot. Since PS4 Pro is big on this new HDR, I will be getting this model instead XBR55X930D. The XBR55X850D is also a really good TV for 4K HDR. To those who purchase the XBR55X700D bundle, I'm sure you'll love the 4K but you will not be able to enjoy everything the PS4 Pro promises in picture quality. Cheers, JW
