Having just got this tv in a 65 i have concerns about the near black problems i seem to keep reading about. Everything i have watched so far looks as good or better than my 3 yr old Panasonic 55 oled. Are these problems real or just people being fussy. Im not really sure what im looking for but am considering a calibration which i dont want to fork out for if there are problems. Any pics or scenes to look out for. I watched retun of the king today on 4k blu-ray in dv bright and was blown away.
