In my edit I used the L channel to accomplish something similar. But both our edits differ and using the h channel seems to be working better for yours.
I really don’t know what the greens in the original scene looked like. I never look at the embedded jpegs to be honest. Those are created in camera by (closed source) algorithms based on settings that will not be present in the RAW. I think they are useless.
There are a whole lot of interpretations present in this thread. I’m guessing that most, including my own, are probably too saturated when compared with the actual scene. So in the end: Personal choice and esthetics.
