I have the DP screen and is a good improvement over stock, especially on track, however as others have noted you can only fold the mirrors forward with this screen.
One other issue with the clear DP screen is that it acts like a magnifying glass and under some circumstances can project a beam of light that will burn your display. Unfortunately I now have a small burn mark on mine up near the shift lights and the dealer isn't sure if Ducati will cover it under warranty. If you fit the DP screen I recommend you park the bike nose towards the sun, or cover the display when you park it outside.
