True uncompressed Video Formats

Hello People,

I'm working on my Bachelors thesis comparing Raw, Log and Uncompressed video formats. I wasn't able to find anything thats not uncompressed aside from oldschool analog film. If you look at what most people call uncompressed it's coming down to losless compression, meaning there is some form of chroma subsampling behind it. Technically RAW files fall in this category too.

If you have any good rescources, please let me know!
