anytime you view a thumbnail of a RAW file, its a jpg. Anytime you view a RAW file in Lightroom, it's a 16 bit tiff in ProPhoto RGB.
RAW files cannot be viewed, they are just data. This is why Lightroom builds standard and 1:1 previews when you import them. This is also why no pixel distortion can take place in LR. Only changes that can manipulate the dynamic range of each pixel (color, luminance, etc)
Lightroom is non destructive... any time you make a change, you are just adding a line item to a database. The changes are actually executed when you export the image to another format. Lightroom is brilliant in this aspect. You never have to hit "save".
Always shoot RAW, unless your editing environment simply cannot handle it. RAW files have such wide dynamic range to work with, in both color and luminance.
