Pretty sure that video was subsequently derided for being mostly inaccurate?

The whole “4K Era” is riddled with these sorts of problems. The tech was sorta rushed into place, and gimmicked to hell and back as it got introduced, and as such you have a ton of people who don’t really know what it is, what it can do, and how it does it.

But they all seem to have various ideas on how it gets done WRONG, haha. If anything, the primary lesson most people seem to have learned from the 4K era is that most everything isn’t even MADE in 4K. It’s gotta be sort of disillusioning to spend all that money on all those “Ks” only to find out you weren’t able to really tell the difference between 2 and 4k the whole time - and still can’t.
