That's another ignorance here.

The picture is bad quality, but as I stated one can read the information out of it. It is not a coincidence the colors teal and orange are dominating.

You can't also really say the color-grading is not final. Because movies are not a production that works in incremental steps, as the color-grading will be upgraded to the final look and become better. The initial look is right there. The only thing changing will be minimal cleanup in various elements. Not the general look.

Pandering a defined look over a final movie is not what I would call a creative process.

Let me throw an analogy in here. If a ugly girl uses makeup just like a beautiful girl, they will both look similar but the former girl will look beautiful in an artificial way.

The same argument is made about cgi effects. They do not upgrade them as if it's some kind of a software. The final composition of a movie or scene should be there right from the beginning. Software solutions to clean up and alter images are, or should, only be additional tools to be used if they are appropriate.

But in modern movies I guess the color-grading and post-processing is already strongly integrated and pre-calculated, going from that how can you even have any dynamics in the process? No the look is basically pre-calculated from the beginning. Because there is too much money involved to be dynamically. This is a bad thing right, because movies are always a dynamic process and not a stiff production enterprise.
