Yes, and did you actually take a look into that? I made the point in another comment: What they provide is either cherry picked assets, doesn't even work properly until you do quite a lot of plumbing or it shows how much is actually "hand crafted" and not using engine specific things. For example you import a captured model and animation that is basically just keyframed vertices, while they claim how cool and procedural their animation toolchain is ... That's not how this works. Unreal does this kind of specific customization for demos, too ... but on a much lower scale. Unity demos barely show actual engine features but are just made to impress the general layperson.
