semilog
curmudgeonly optimist
from early samples it looks like the "cost" of this reduction in watercolour effect is some image softness in the conversion. can you confirm if that's what you're seeing semilog?
As others have said the default is a little soft but you can hammer the files with the sharpening and clarity sliders and extract fine detail out to the pixel level. There can be a little mottling when you do this as with files from other sensors but it's really minimal.
For me the acid tests will be pictures of foliage and pictures of people. I've looked at the foliage but not the people, yet. But so far this looks really promising. I'll add that at least up to ISO 800 little or no noise reduction is needed. Certainly, the Adobe default values for NR are much greater than required.
