Wide Color Capture is the iPhone 7's key new feature ...
Starting in mid-September, and if using an appropriate Apple mobile device, photos captured with "wide-gamut" reds, oranges, yellows, yellow-greens, as well as red-violets, will significantly standout !
So much so, that we (boldly) predict that many Advertisers, and especially those in the female swimsuit, active wear, & lingerie industries, will immediately begin to focus on those colors soon-after Apple's annual September iPhone announcement, when this knowledge starts to become mainstream.
We believe Wide Color Capture (WCC) will be supported only on the iPhone 7 and 7s, as well as on the existing 9.7" iPad Pro.
We also believe Wide Color Display (WCD) support will be limited to those three mobile devices, plus the 21.5" 4K iMac, the 27" 5K iMac, and the yet to be announced stand-alone 27" 5K Display (which we expect to be announced coincident with the iPhone 7 and 7s, for obvious reasons).
Consider it to be this year's Live Photo-like surprise. In fact, the next-generation of Live Photos, out at the same time, will include support for both WCC & WCD.
