> They successfully show that Niemann was playing many games with a high percentage of "engine perfect" moves, but they do not do enough to show that this is inconsistent with what top players usually do.

I thought the video very much did make that case. A single known cheating game had a 98% correlation (Sebastien Feller Paris 2010), other GMs have generally at most 75% average correlation. The analysis had more than half a dozen games with Niemann at 100% correlation. If that's cherry picking, it seems like there are a lot of cherries to pick.
