Keanu looked insanely good at the beginning of the white room scene, but then I realized it was real footage when they switched to the uncanny-valley-esque version at 1:41…
Right. The team behind this is being a bit dicey with the truth. They never seem to be clear which parts are CG and which are video. Any time Keanu looks goofy, that's CG. It looks hand-animated to me because the movement is so terribly poor. Mo-cap to me is still shitty (see e.g. Thanos in Avengers), but hand-animated is always uncanny.
The article seems to suggest that's all real-time rendering though?
Even the scene from the original Matrix shown on the TV?
