If you zoom in and trace the “collar” down looks like maybe could be some kinda vegetation vs collar.
The camera is at almost the same angle for both. Look at the one without the collar. There is nothing in front of the down tree that would make a dark streak like that.
Otoh, the 2d pic shows it almost head on. It's possible that it's the same animal but it's just turned so the collar isn't visible. Otherwise they look very much alike.
