I disagree about a 4K scan being pointless. It doesn’t matter what resolution the original digital source was. The print needs to be scanned to preserve the unique version of the film, and the scan would benefit from the higher resolution, which better reproduces the grain on the print. Scanning in 4K also means it can be released in native 4K for those who want to watch a 4K version.
TPM has what, 70% or more shots with digital effects? That’s most of the film that’s maxed out at 2K. But it’s still worth a 4K scan of the print.
