I don't think that's correct; they seem to have no effect on ball placement, either in-bounds or out-of-bounds. As slydways has said, their purposes seems to be only visual; without them the white lines in the distance blur away to nothing, so they seem to be there solely to ensure sharp lines are visible further away.
It may be possible to do write a script for Cheat Engine to do something with this, but that would be calhoupe's area.
Great sounding mod though!
