I think the Marvel example is interesting as much because it doesn't seem to just be trend chasing, but also one axis to view Marvel's internal struggles between homogeneity and experimentation/directorial control/capturing the joy of the art of the comics themselves. You can almost directly tell if it was a year that Marvel studio choices were more dominant or if the film's director and editor had more control that year based on the color grading alone.
