Play for Discussion: Incidental Contact or Foul

On this play, we have a legal screen set by Red #22. When setting a screen outside the visual field of a moving or stationary opponent, the screener needs to allow for the defender to stop or change direction (moving) or a normal step to move (stationary). White #0 has enough time to stop and/or change direction, so the burden of subsequent contact is placed on him. By rule, inadvertent contact that occurs when a screen is set outside the visual field of an opponent can be severe, but still be considered incidental. However, the better choice on this play is to have a whistle since the contact that occurs could lead to rough play if not addressed. The trail does a good job of refereeing into secondary coverage by finding an active matchup and putting a whistle on this play. Does your opinion of this play differ?
