Sitting here watching The Arrival, 4k HDR. Panasonic 802 HDR Optimizer is turned on, Dynamic Tone Mapping on my 55" LG Nano tv is turned off. I notice in dark scenes, when there is a local area of brightness there is an obvious area of faint brightness in the picture that flickers as the bright area moves in the scene. Outside the bright area the the picture is darker. Is this in the movie itself or do I have a setting wrong?
