I've just opened the first image in Bibble and there is some noise in the white building and also the top of the canopy. It's not too obvious at normal size but it is at 100%.
It looks as if there has been some shadow boost to compensate for the high contrast scene - is this the 'Active-D' lighting that people are referring to?
The good news is that it Ninjas out very easily on Bibble's default settings to leave a perfectly smooth image without losing clarity. If that's the price of auto shadow boost, it's not too bad.
