> But the output result is the same

Law is only extremely rarely concerned with only output results and not process, status of actors, etc.

Yes, legally, the outcome wouldd be different (whether it was original, a direct copy, or something made by copying elements but with some new content) because chimps are neither legal actors that can create a copyright through authorship nor ones who can violate copyright.

Interesting, also what do you mean by "status of actors"?

There’s a really interesting adjacent problem - the so-called “monkey selfie” which was recently settled by stating that works created by a non human we’re not copyrightable.
