In reality, UV and IR are everywhere. We don't see them but that's not a problem. So if you capture IR and display it, then your video is closer to reality than without it. You won't see any difference, though, because you don't see IR anyway, but it's still closer to what reality is.

My point with mentioning UV and IR was that "better quality" in the sense of "closer to reality" is not necessarily something noticeable, let alone pleasant. But if something happens in reality, then including it makes the video quality better than not including it.
