That's mostly a problem with the input data. A gamestudio of the size of rockstar could afford to acquire their own custom fit dataset. Get some good cameras and lenses and capture footage of wherever they want to set their next game. Then they can apply some motion picture color grading to that and use that as the input data for the NN.
