Too true, clearly you haven't!
In fairness TV tech moves rapidly and in the past a properly set up Samsung is fine, especially no bigger than 55 inch in my experience. I don't like how Samsung try & build in obsolescence to their offerings though.
I found at the same 'asian cuisine' retailer the LG 65 inch was set on default settings not demo settings and it was all about the black definition. It was stunning. No way does it look fake. Hence why we bought it & once played around with settings we are very happy.
We're not critical movie watchers, we don't own a player DVD, Bluray or 4K and my wife mostly watches crap Thai movies on YT. But it produces stunning images really well... all of the time.
