I think the point is that films are generally shot using a variety of lenses and sometimes games try to simulate these lenses (in this case anamorphic). The issue is that games (in general) shouldn't be trying to simulate camera lenses, we do not see the world through a lens. However, this is down to the artistic vision of the game developer, if they want it to look like a film lens then so be it but that's where the 'filmic' term comes from and many gamers don't like it (I'm mixed, sometimes it works really well such as The Order 1886, but in many cases it doesn't)
I get where you are coming from as both industries do borrow from one another, however, they are very different in that one is an interactive medium the other isn't. So I disagree with you that the film and video game industry are the same, they can share the same tech but other than that not too much, but maybe thats what you meant rather than both industries are virtually the same.
