This DCP has been around for a while and the bd was from the same 4k master.
Well nevermind. Looks like I was wrong lol.
I remember reading Robert Harris said the negatives were horrible shape and likely could not be scanned again back when that ancient VC-1 BD came out so chances are this will either be sourced from the same raw scan or even the same base restoration as that disc but obviously will be an improvement given HVEC + AVC and all being encoded by FiM.
