Still over priced for a clearance model, however the best of tv's (marginally over the MU7000) mentioned by the OP.
Yes that website has it back to front, the Samsung under 55 is 8+2 but everything above 55 is 10 bit (maybe the model in the state 55+ is 8+2?). The Sony is 8+2 not 10. Doubt I will even notice the difference between 8 and 10 bit if I ever looked at them side by side lol Maybe I need to just forget 10 bit and buy a TV as my current one has been broken (lines down the side of the image) for the last 6 months while I try to decide on a tv.
https://www.displayspecifications.com/en/comparison/30f41ca94 Suggests the Samsung is 8 bit + FRC and the Sony is 10 bit, though I think that I read somewhere else the Sony is also 8 bit + FRC. The comparison shows very little difference between the two and the best comparison is surely seeing them side by side with the same content playing. I too have been very interested in the Samsung, but when I saw it alongside the 8396 my preference was the Sony, the 8596 in this deal was better still (again only in my opinion).
Heat added but not 10 bit, which in this price range only the MU7000 55"+ is, only issue I have with the Samsung model is the stand and this is stopping me buying it.
I am in the same situation. Same TV. Looking at an increase - just trying to weigh up the pros / cons and which tele I would get.
