Samsung QN85D Netflix and bending

Hello guys, I bought the 75" QN85D as I found it in good price. I have 2 questions if any of you can answer. On netflix the movie isn't full screen and it has 2 black bars top and bottom. I tested in two movies. Is there a way to fix it? In the settings I couldn't select the aspect ratio as it was gray the field.

My last question is the bending. I feel that the whole tv does a small bending to the back. So the top part of it, it 2cm more to the back than the bottom part.
