I dunno maybe I'm drinking the kook aid but I feel I have the same issues but not all the time. Some daytime shots come out stunning other times especially with leaves on trees you get that watercolor effect. If you don't zoom the picture if looks absolutely stunning but once you zoom it can become a muddled mess.
Shots with less than perfect lighting suffer from this more. I'm going to try shooting more often in LR seems like it doesn't suffer from this issue in DNG format
