I wonder why the returned stage has a white band in the middle with less soot than above and below.

The return streak looks shallower, as if it's walking the IIP from off shore to the pad.Yes, but don't forget the rectilinear distortion in the wide angle lens. Something in the corner of such an image can look quite crooked and still be vertical in reality.Agreed. Hence my hedge... but the difference is really noticeable, and the streaks are not THAT far from each other.I also realize there's an angle change wrt the camera, irrespective of the lens effect.Still though.Here is another image, from SpaceX. It looks much more vertical from this point of view. It is coming in a bit from the side (the nearer streak is the landing), but it is hard to tell how much is from the trajectory and what is from a divert maneuver.

If the white part is the LOX tank, what's the ~10 m of stage between the white part and the interstage for? The upper dome of the LOX tank is probably about 2 m of that, so what's the rest for?
Is it just me or does it looks like there's some cracking under where the landing leg was on the left side of Elon's video?https://twitter.com/elonmusk/status/679145544673923072
