I am currently using a Sony X-700 4K UHD, I am going into a 2018 E series OLED, One of the things that I found interesting was the Tone Mapping of the Panasonic, I am trying to decide to ditch the Sony and get this Panasonic, I have not had a single issue with the Sony and the picture is very nice, however my OLED has Tone Mapping when HDR content is active. I guess want I want to know is those that own this player, do you think it would be a worth while upgrade for me? Would the Tone Mapping in the Panasonic be better than the tone mapping in my OLED? Also, I have not seen this, but does anyone know if they have made the Panasonic 820 ABC and dvd region free with a mod? I am debating paying too much money for an Oppo 203, or getting the Panasonic, or just leaving the Sony in there... Thanks!
