Yeah I noticed that but the boundary line SEEMS like it shortens the stadium but unfortunately, when playing it is not much of a change. Sure it is a bit shortened but Lets say I am playing in a very big ground and I have a batsman with yellow bar and I loft the ball and get a Good, Ideal, Ideal. It goes for a catch. Similarly, when I do that in smaller stadiums too, it goes for a catch. Just a note, I just tried this once. So if someone else has more experience in this, I would be thankful
Edit: How does stadium shape affect size?
