Can’t say I would agree on this oneHopefully you're not going to Currys or JL as they will not let you bring your own material or equipment into the store. Currys told me it was a health and safety issue. I went to my local AudioT to look at a Panasonic FZ802 but just took a couple of blu rays that I knew well to see how the TV handled them. Not scientific but I know I've made the right decision. There's nothing to guarantee that the TV you buy will be anything like what you see in the store such is the lottery of OLED panels. I think you can gain more information off the owners forums on here.
