It’s weird to see a SE presentation look so… filmic. It honestly looks like 4K77 more than the BluRay.
IIRC the Lowry/Reliance scan was made from the Special Edition negatives, and then had the 2011 blu-ray changes applied to it (as well as the MacLunkey and other minor fixes) before being finished. So if it looks more filmic, it’s probably due to that.
