Yeah... Unity compress the renders into his own raw format.
So far I have seen two ways how a Game Dev could "compress" his/their game:
1. As mentioned above: Using Unity's own Raw format (e. g. MotH, Midnight Paradise, and almost all other Unity Games)
2. Accessing through an archive file from the Streaming Asset folder.
Latter is used by Timestamps, where all renders are convert from jpeg (or whatever) to webp format.
I'm not sure if Faerin could import his video files to Unity, to use Unity's Raw file, since he use a 3rd party plugin and Timestamps for example use Unity's build-in video player for animation playback.
However, both Devs of both games use the most compressed version to distribute their games already. A further compressed or crunched version as seen for Ren'py games is not possible, because:
a) Dev use Unity Raw file for renders,
b) Dev already converted all JPEG files to webp.
The funny thing is: All "crunched" Ren'py games are nothing as converted JPEGs to webp with reduce quality (90% instead 100% quality).
I know I don't have to you tell you all of this, because you are aware of it and we might had this conversation already
Anyway, for more information I would recommend this thread by Sam.

@medo12345678: Those are some technical background information which might help you to understand, why you can't compress or crunch Unity Games like Ren'py games
