Sure, I can't say - but when was that made part of Rec 709? I suppose that may well be what it invented...
Edit - to clarify better that what I'm trying to convey is that the time and context matters too, and the claims have to be read in light of the description, so suggesting that claims are trivially invalid is something to be cautious about.
Rec 709 was published in _1990_ (and had that gamma structure then, of course!).
All you can say red is doing is reciting the rather obvious combination of a 2k+ camera with rec 709, 23+ fps, etc.
Maybe it's the case that someone can't find a 2k camera being offered to the public early enough to invalidate on a prior art basis-- but I can't see how anyone could conclude from this that a red success would be indicative of anything but a deeply flawed patent system in dire need of reform.
