Interestingly the Hot Toys JL Superman does give him that vibrant blue. There’s a featurette that WB made with costume designer Michael Wilkinson explaining how the blue suit for JL had more chrome and was a more saturated blue color. That’s because Geoff Johns wanted Snyder to change his version to Josstice League, but Zack knew for his director’s cut he’d make the suit black anyway. It has absolutely atrocious color grading in Whedon’s version, looks more turquoise. But anyway, I do think the brighter blue of that suit is what we would have gotten for JL 3 where Superman completes his arc.
So that would have made it...5 movies in before we got a brighter, hopeful Superman?
