While Nikon prosumer cameras are delivered with a plastic screen protector, « pro » cameras are not. What I know for quite sure, is that the screens of the pro cameras are from mineral hardened glass, which is « unscratchable », at least under normal circumstances. Personally I didn’t made any scratches in my single digit cameras (D4s, D5, D6), neither my D850. While I initially followed the trend of applying glass protectors to the rear screen, I quickly abandoned the practice, starting with my D5’s, to never come back. I follow the same policy with my smartphones. But I am a person who handles his equipment carefully, even used professionally. Hope this helps.
