Disney's latest CGI films are rendered on a much higher resolution and with multiple denoising passes and other settings set to max to hide even the smallest instances of grain. One would get a similar result with much less time and the differences would not be noticeable for 99% of the people, if they were to turn down some settings a bit.

Is that to let them create something like a (say) 16K archival master that covers all the formats they might want for the foreseeable future without an expensive re-render?

Rendering at a higher resolution than the format target and downsampling to the target provides anti-aliasing. Gives them the "CGI" smoothness.
