Oooh that’s interesting - I’d been aware of the color space encoding, but hadn’t fully grokked how it manifested.

It’s interesting because it straddles analog & digital so many times - film is a chemical process, broadcast is an analog process, CRT screens are analog processes, and at the end of the whole thing, our eyes are an analog process, so you’ve got this wonderful bundle of path dependency (B&W -> Color, Analog -> digital, film -> broadcast -> DVD) where you’re trying to capture the characteristics of a dozen different physical phenomenon so you can throw a photon into someone’s eye Just Right repeatably.
