Attached is a photo I took with my iPhone and then cranked the brightness to exaggerate what I think you are referring to.
In the image, you can see the pixellated dark grayish background, but you will also notice the inky black letterbox across the top, and my bias lighting to the right.
The dark scenes in Dunkirk are a challenge for any TV especially OLED's. I believe what you are seeing is caused by two things:
1) Dunkirk was shot with film. Film is never completely black, and Christopher Nolan would never allow any digital transfer from film to "add" blackness or artificially increase contrast. If the blacks were actually elevated by the TV, the letterboxes would also have a hint of gray.
2) There comes a certain point where an OLED light can not get any dimmer than to be completely off. If you have ever tried to dim an LED light bulb, you know how it will attain a certain incremental level of dimness, and then it will not get any dimmer. At that point, it gets very binary - either off or dim. A similar phenomenon is also happening with our OLED TV's, and it is especially difficult for an OLED TV to come out of black gracefully. It's getting better, and FW 4.70.xx made huge strides in that area.
My two cents.
