I just skimmed this but if you try any sort of color correction in a non-linear color space, e.g. display-transformed sRGB, your'e in for a world of pain. What R, G & B mean must be known exactly, otherwise you may as well be rolling dice. G = 1.0 has a completely different meaning in sRGB, ACEScg or Adobe ProPhoto. And even what 'white' means depends on the color space you work in. I started in commercials and VFx in the 90's when almost all places I worked at had poor at best incomplete understanding of color science. Allmost all rendering, grading, etc. was done in the aforementioned (display-transformed) sRGB space. So while there is the aspect of how something should look which I understand is a huge part of what this PDF is about, there is also the part of how to attain that look, once you know what it should be.
