I've got an 80" Samsung in the great room and a 55" of the same model in my bedroom. Unsure of the model number but they are about 5 years old and I'm still impressed every time I watch TV. I'd like to get a 4k but I don't watch enough tv to justify the spend; especially when nothing is wrong with what I currently have.
In retrospect, I see how pointless my entire post in this thread is. Completely devoid of any information aside from my own logic. You're welcome.
