Bought and installed the exact model from richer sounds a couple of months ago for my parents they are over the moon with it and I can't fault it one bit. They dont care a jot about HDR or how black the blacks are, they just wanted a TV they could turn on and had a big screen. They didnt even know where the picture menu was on the previous TV...
Honestly everything looks absolutely fine to my eye and I'm sure there are experts around that could pick it apart for issues but if like me you just want to turn it on, get a nice picture quality that you dont have to worry about I cant think of a better recommendation. It felt responsive enough for navigation and all smart services worked perfectly as well.
