I think saturation and contrast isn’t really the issue for the 19SE. Overall the color grades are pretty cinematic. It’s the lack of color dynamics in the color grading, which make them look quite flat. Here’s a regraded frame from ANH:

There’s many more shades of red/orange/pink in natural skin tones, or even in the red panel in the back due to lighting effects. I don’t have the original D+ frame on hand right now, but the colors are all flat, and rather monotone, if you understand what I mean.
