Do you have a detailed suggestion for such a method?

It can work, I just think that nobody wants to tweak this for a movie,
since when you finished tweaking it for one scene, it may look bad in
the next scene. The current matrices are intended to be ok for most
video content, but of course constant matrices cannot be perfect for
every scene.
