My new LG 65UH615A has something called "HDR", which seems ridiculous, since the peak white point is less than 200 nits.
Anyway, when I play an HDR show on Netflix such as "The OA", the TV switches to HDR picture mode, which raises the black point and makes dark scenes look washed out. Bright scenes look pretty good. How can I disable this and go back to the "Expert dark room" mode?
