Hi Russell, It think this is to expected as the lightable images will for speed be derived from the embedded jpeg's in the raw file and hence have the camera's colour correction applied to them. When you go to darkroom mode you are then opening the raw image itself and will have no colour corrections (apart from any defaults) until you start working on the raw. The banding is probably because the embedded jpeg has more limited bit depth than the raw image.
There is I believe a preference setting to turn off use of the embedded jpegs in light table, which would avoid the effects you have observed at the price of slowing things down. That isn't something I want to do myself so I haven't experimented with it.

Usually I assume this is a trick of the eye (brain). But just now I have found one that is obviously so. https://www.dropbox.com/s/4an7w05ncqsfcaz/IMGP0214.DNG With this image, click it in lighttable and hold 'z'. You will see an aqua-blue sky with obvious colour quantisation banding. Now double-click to darkroom and you will see a more purple sky with no banding visible. At least - that's what I see.
