That's why I stated ~4 years and not 4 years ;-) (when you retire, time just doesn't hit the same).I think it has only been on the market for around 3.5 years though. I've had my 48" model since release and also no burn in. I think I have over 6000 hours on it.
If you use it, how do you feel about the Samsung smart TV stuff vs LG WebOS? WebOS has been pretty solid for me but I loathed the Samsung software on the KS7005 I had back in the day so much that I bought a Chromecast Ultra to use with it.
I don't use the smart functions of the TV. The Samsung looks to be better for options, but I dislike how I have to select the PC input nearly every time that I power it on. With the LG, it was just in that mode when powered up.
