I really appreciate all of Your nice feedback.

Great observation! When increasing the exposure with the ofset controls (+R +G +B), the algorithm favors the red chanel in terms of total density compared to green and blue. "Red has a total density value of 37% of 1/12th of a stop or 3% of a full stop" as explained in Dan's article. Do you know if the relationship between R, G, B is unevenly distributed in terms of saturation as well? Or is red only overweighted compared to other colors than blue and green?

I think a big problem with classic saturation is, that the tool is not colour space aware. The results are different, when You are applying it in 709, AP0 or WideGamut for example. Every time overweighing different colours, depending on the gamut it is applied in.

Additionally I have the feeling that the secondary colours C,M,Y are always a bit less favoured in classic saturation tools compared to R,G,B. I am not sure about the reasons for that. Maybe it is because R,G and B have more space to move in the gamut, or maybe it is because they can achieve higher saturation values in the display (which is also working in RGB). 

And on top of that: Our perception of colourfulness is probably not working like a simple technical RGB colour-space, but much more complicated. 

For me the look of the movie was the star! Magnificent work, Eric.
