Mars over Miami 2: use 12 bits or 8 bits?

As Trevor and my wife Gail pointed out, my Jan 20th image made Mars look like it is laying on a slab in the morgue. So I redid a set of 1500 frames taken at 30fps using the 12 bit mode of my new Dragonfly2 camera. This is the image on the left. Does this image capture more detail than the image on the right which was from a set of 1500 frames at 60 fps (8 bit)? Maybe. Maybe not. You be the judge.

The awful color was the result of a Photoshop screw-up. Now things are under better control. I would like somebody's opinion on whether it makes sense to use 12 bits @ 30fps vs 8 bits @ 60fps under average seeing with a bright planet? I am under the assumption that the larger grey palette at 12 bits only becomes important with dimmer images that will have to undergo stretching.
