M4 or M4LE?

[Spartan198]

I'm going to be screencapping Inside Eden's Gate, a tie-in prequel short film to Far Cry 5 made by Ubisoft. As probably expected, there are quite a few of what look to be M4s in it, but they're all notably only fired in semi-automatic all through the film although no close-ups of the fire selectors were ever shown. Would this alone be enough to consider them M4LEs aka LE6921s rather than actual M4s?
