Here are a couple of videos about color that I enjoy and find very informative:
Captain Disillusion: Color
This whole channel is great VFX reference.
Minute Physics: Computer Color is Broken
This one is great for learning more physics, if you’re into physics, cos physics’s cool.
Good suggestions. I really like that one that you did
UHD TV - From Lens to Lounge Room
I thought this was an interesting video covers a lot of things: Pointer’s gamut, the Plank curve, a good description of OETF-OOTF, HDR etc
Interesting perspective on HDR & film prints / projection
