Hi @kazah7, thanks for the feedback!
To answer your questions (and also @sguyader in part) :
Well it’s also a matter of finding the “sweet spot”. If you are talking about the desturation in the shadows, the tool tries to raise the chromaticity when pushing shadows, but currently it’s a bit conservative. I can try making it a bit more aggressive. If you are lacking local contrast, well there’s another tool for that 
(if instead I just didn’t get your point, please clarify, thanks!)
Hmmm:

better now? (I have no idea how the lightroom slider works, but I suspect there’s a lot going on behind that simple slider…)
