Your criteria are unclear, what counts as real life footage? Captured bdrf? Photographic textures? Photogrammetry? Motion capture? Made by an artist equipped with lots of reference?
But, those are all examples of why photorealistic CG is fiction. We've never achieved it in video.
I'd like to dig further into what you mean by photorealistic CG being fiction? There are still tricky areas that are actively being researched, but I've seen plenty of CG assets that are photorealistic.
What do you think is technically missing from CG video, that makes it lack realism?

If you approach the subject with an open mind, you'll find that we really haven't achieved those goals. But the most I've managed to wring from people is a grudging admission that even though we haven't done it yet, we could do it if we tried. I disagree.
