Remember Paramount recently did amazing remasters of Wayne’s World, Truman Show, and many other films where they restored or fixed elements from their original Blu-Ray format releases. There is more care in the UHD division than there ever has been. There is no way they would fake gate weeve or fake film grain that’s just a bad faith assumption

Truman Show had wrong color grading and companies do fake film grain and gate weave. Studio Ghibli films do it all the time. Disney and Warner Bros. constantly use fake film grain especially in more recent remasters.

You’re presuming the digital elements are still there and weren’t corrupted or rendered inaccessible due to several factors. Few, if any, studios outside of Disney and Pixar were that careful with the preservation of their digital assets and the legacy software/plug-ins used to generate visual effects and composite the final frames. The Iron Giant, Cats Don’t Dance, The Prince of Egypt, all three theatrical Rugrats movies, and even Disney’s own A Goofy Movie were all film-sourced for their high-definition transfers because the digital sources and programs used to composite a scene were either misplaced, damaged, or the company simply did not see the need to re-render the film shot by shot due to missing assets or an unwillingness to put in that much time to retrieve data that may or may not even load properly.

This is correct, however, when they made a transfer for the Spongebob movie on Blu-ray and HD broadcast they would’ve had an uncompressed digital copy made available. Disney and Pixar have done it but some of those machines likely don’t work any more. Once you do it once, you don’t need to do it again since it’s a perfect digital recreation. Disney has reused those same digital copies for their UHD releases which is why you’re stuck with altered versions of The Lion King and Beauty and the Beast. Those are the finalized versions they decided to backup and likely can’t access the originals anymore. None of your examples had digital to digital releases before, but Spongebob has.

Yes, companies do fake gate weave for NEW movies NOT remasters to give an old or nostalgic aesthetic. “Fake” film grain in remasters is actually not fake a lot of the time. It’s usually the grain from the actual film removed and replaced after clean up. It’s usually the real grain from the film. And if fake grain is used there are rarely any cases I’ve seen where it looks bad or out of place. It’s an essential part of remasters to degrain to digitally clean and restore film. Another thing is film scans a lot of the time have more than just FILM grain. They typically have noise from the scanner’s camera on top of grain from the film. Denoising scanner noise is imperative if you really want a true authentic picture.

Also, a note about Truman Show is from what I saw on a true 4K HDR display was fantastic. Not sure what you mean by “wrong color grading”. As someone who has watched the film about a thousand times and has had a lot of issues with the original Blu-Ray and DVD releases the UHD is the best the film has and will ever look
