If RAW retained the original processing applied in-body by the camera, including color modes and sharpness adjustments, then it would be far more useful. But I can keep dreaming.
You don't say what software you were using, but as others have mentioned, the Pentax software will listen to and reproduce pretty much all camera settings. Other programs generally at leats try to reproduce some options. ACDSee Pro, for example, will increase sharpness and saturation if you set those in camera, but that may be about it.
On the other hand, also don't find it particularly difficult to adjust color or anything else the way I want. Nor do I think of reproducing what the camera did to be my ultimate goal. Especially with sunrise/sunset pictures, where AWB usually washes out the colors terribly. I find setting the WB to "flash" is often the best way to capture strong lighting effects. Doesn't matter whether you do in in camera or in PP - takes but a second or two either way.
