Why would snyder release the first official trailer going through the effort of making a scene looking a certain way using filters if he planned on changing the filters later that doesn't even make sense. He would have just done it from the beginning
Snyder is on board he releases a trailer and scene looks one way. He's off the project and then the next trailer has the colours and filters changed after another director comes on board. This is not rocket science people.
What's next,are you guys going to claim snyder always was going to bring Elfman on board as composer
