Way back when it was decided to call it "RGB24" even though what is being
returned is "BGR24". I don't know why, but the symptom of having the
values reversed is usually a very blue image. Since the first device to do
this was the first V4L device (bttv), most drivers have kept bug
compatibility and return data with blue in the lowest order byte.
Try swapping your Red and Blue bytes and see if that gives you a better
result. What you are describing is exactly what I saw with the driver I
wrote when I was returning RGB24 images as RGB24. So I added a driver
option to swap the two and everybody was happy.
