Why should he? He isn’t arguing for SD capture/presentation or any nonsense like that.
Well the artefacts are certainly still present in HD resolution as well.
He mentioned the IMAX and 35MM being the same stock. In any case, I’m quite content to trust that this guy, who…
-has shot 13 features on film,
-is been somewhat nerdy about his tools,
-is part of the AMPAS Science and Technology Council,
-had their conclusions endorsed by the president of the ASC,
-is lensing the new SW film,… probably knows enough about what he’s doing such that the question of “if he used the right film stock/scanned it correctly” isn’t one worth asking.
It doesn’t change the fact that he didn’t tell us what film stock he used, he just said 4-perf and 15-perf negative, he never specified what stock it was. There may just be one standard Kodak colour negative used at the moment, I don’t know, but we don’t know what he used.
