So just to clarify, the single frame technique corrects all resulting frames in a single color space?

If so, is there a chance to implement a third option, where the original image is corrected, saved, and then the multiple color space model analyzes the source image and uses the new image as the reference? I'm just thinking that some images in the film may require a little more force to push the correction. Or is that assumption incorrect?

That would not work, because the multiple color space method would essentially immediately converge to the single color space method, because the initial correction effectively removes all the color information in the other spaces.
