The notion that antiglare film is used in an attempt to boost the stability of the flat face of the tub is very difficult for me to believe. There is absolutely zero chance that the tube in the N and the standard models are different in any way. The front face of the tube is absolutely the weakest point, when that front is flat, but this is why the frame of the tube is so damn heavy, all up at the front. The heaviest, thickest steel is used there, and its entire purpose is to hold the tube and prevent implosion. Any safety notes in the manual, consumer or service, is absolutely there to caution against removal for potential damage to the tube in the removal process.
