Chris Farley Shrek videos

Years ago, some videos of Chris Farley's voice as the original Shrek wound up online. One is a storyboard (https://www.imdb.com/title/tt21797660/) and the other a test animation (https://www.imdb.com/title/tt21803526/). They were uploaded by people involved, from what I understand as animators, in the production. I contacted IMDB for deletion of these titles, because in my view, they don't belong on IMDB. For one, they are unauthorized releases, basically bootlegs. Not officially sanctioned by DreamWorks and uploaded on a Vimeo account by someone who worked on the project. They were meant for internal use only, and on one account I know the original uploader deleted his video after it got reuploaded on youtube. IMDB first said they'd 'carefully' looked at the case and saw a release date of 2013 on IMDB, indicating it was released and they weren't going to remove it. When I got back with some more of my reasoning, it again got declined. It still doesn't really sit right with me, so I'll just try to ask this here. These titles never got out on an official basis. If we count that as official releases on IMDB, do we also count leaked videos of tv-shows as the original release date? As I said earlier, they were meant to be seen only internally while working on the picture and they did not get released by DreamWorks. Unofficially released videos. When I posted something about the wrongful early release of Bad Trip (2021) that got accidentally released on streaming a whole year earlier, it was decided that that earyl release date didn't count as it wasn't intended by the production or distributor. Does that apply here too? I'm curious to hear other's thoughts on this.
