I leave it to the experts.

I watched both, and I cannot tell if one is really doing a better job with DC restoration than the other. The "good one" looks like it has some too-dark objects in some high-contrast scenes, which will help with dark areas in other scenes, and the "bad one", besides having ambient light that makes it harder to evaluate, is not using a very good program example. That program seems to have about the same amount of light and dark areas in every scene (and is a very old video itself apparently), so it is hard to judge.
DC restoration is a great can of worms to open! I have never got the exact hang of how it works when it is good, and what is wrong when it is missing. I love how good my RCA 8TS30's picture looks with its good DC restoration. All the black-and-white sets I ever saw when I was growing up had none whatsoever, and I still remember being amazed watching my brother's Sony KV-1920D 19" color set that he bought in early 1977. "Wow, night scenes make the TV screen go DARK! And, the screen goes black between commercials!"
