Aplogies to all if discussion on my query exists somewhere but I own a Sony BDP S7200 Blu ray player and a Sony KD65 9005b Tv which whilst not HDR, does have extended dynamic range. After picking up both versions of the panasonic UHD player and altering every setting available, I cannot get a picture which anyone in the family feels to be an upgrade and the OH is adament of it being a downgrade. The issue being that the images are duller and lack "pop" in comparison to the Sony. We've spent a good number of hours playing BD vs BD on different inputs and also UHD vs BD advancing chapters and switching inputs to compare. The UHD pq over upscaled BD is also something non of us can see. I have read some discussion of this and also notice the amount of UHD players going up for sale, yet most of the reviews suggest large improvement. Is it that the Panasonic colours are more accurate and the Sony is more saturated ? Are we missing something ..........?
