The truth, as is usually the case, probably falls right in the middle.
While there likely isn’t a traditional “Zack Snyder Cut” of Justice League, the way that there was an Ultimate Edition of Batman v Superman, there probably is a version that plays out differently in key sequences.
The resurrection of Superman, I’m willing to bet, played out differently in Snyder’s head than it does in Joss Whedon’s delivered print, and I say that because of the CGI jaw that Henry Cavill wears in his interactions with the League in that fight.
We know that his mustache had to be doctored in post for the reshoots, and this scene looks like it was tinkered with the most… meaning that Snyder probably had a different version, and the studio paid to change it.
