And what I meant earlier was literally not screen corners, but edges: generally speaking, the further away a point is from viewport center, the greater is distortion. The greater is the field of view, the greater this distortion is. In other words, distortion is always there (yep, in any game, at least of those that I know of), it's a matter of "how much".

PS. I've recently checked: AngularAngle parameter is horizontal field of view for the camera at 1x zoom.
