It's so hard to say something looks like this "in the film" and doesn't look like that in person. The cameras capture things differently when things are being filmed. The lighting is usually manufactured, and the way they shoot the scene can make such a huge difference as to how the props appear. Sometimes things that are glossy appear flat, and sometimes flat things appear glossy. It depends so heavily on how it's filmed that until you see the movie prop in person, in natural lighting, you might as well take Anovos' word for it. And like others have said, there isn't just 1 prop they used during the film, so you've probably seen 3 or 4 different helmets.
