I have a sweet new (yesterday) LG Oled 4K with Atmos, an Apple TV box, and a new Panasonic UB9000 4KUltra HD Blu-Ray Player with WiFi for my home AV system. I am trying to get the best picture and sound. Question: If I want to stream movies (new releases, Netflix, Amazon Prime, etc) will I obtain the best possible picture and sound from apps on Apple, the LG Oled, the Panasonic, Cable provider (probably not), or something I haven’t thought of. I realize the best would be 4K Blu-Ray discs on the Panasonic. But what about streamed movies?
