Does Dremastered use AI or no?
Also, if the 4K versions are AI-upscaled, are the 1080p versions AI-free?
There are no Native-4k-Versions of these movies out there unless you count the 4k-Scans of the cinema prints made by fans (which have a lot of grain and artifacts).
WB/Peter Jackson created a 2k-DI back in the days and even the official 4k-Bluray is based on that 2k-DI, meaning they had to upscale to 4k.
DrDre’s version is based on the Extended Bluray (1080p). He regrades the movies, uses digital effects to remove the edge enhancement present on the bluray and upscales the footage to 4k.
