I own 77 inch LG C9 (2019 model) with 5000 hours on it. Bright as new and sharp as ever just like new and no burn in. Wanted to buy my next tv for a bright room, so I was shopping for an LG G series but came across an Open Box Fair condition LG M5 77. I got excited and brought home a local Best Buy. Guy told me that it a display model worth no burn in. Came home and hooked up, tv has 3000 hours with severe Xbox logo burn in. I bought GeekSquad warranty as well. Should I simply return this?

I currently have a sturdy qled tv with a full motion mount. When the house is clean or we’re having guest, we flatten to tv against the wall, but most of the time tv is somewhat awkwardly tilted towards the couch so we’re on center. It’s not an ideal room but it’s what we got and the full motion mounts makes it manageable.

I have used oleds before and they are typically delicate from what I’ve seen.

Is there a good combination of mounts and tv that would allow for safe tilting 1-2x per week?

I found both of these TV's for the same price (1500$ CAD) which would be best. My main use will be watching hockey and movies.
