Return it and get a Samsung equivalent TV........Had a couple of Vizio TV/s that I replaced with Samsungs........
I prefer Samsung as well, however I've had numerous stinkers from them, Sony, Panasonic, Viewsonic, Vizio, etc. I learned years ago not to judge someone's brand preference since most are essentially the same and its really up to the viewer's preference on what kind of color saturation they like. I personally like Samnsung's color way better than Vizio, while others think I'm crazy. I've seen many Vizio TVs last just as long as Samsung.
I have had three 70 inch Vizio Tvs run one of them 24-7 burned out the LED on the first one but had extended warranty and they sent me a nw one. I buy them because they are affordable and I was in Costco last week they had 75 inch Vizio for under $900.00. SamSung has had some big sales lately also but they are not king of the Hill they once were. I use the Vizio exclusively as a computer monitor never turn it off watch TV in a window usually but can do full screen as well.
I replaced an old Sony with a Vizio 55” UHD this past February. Thus far I’m very happy with it. Never been a fan of Samsung. Just had to take apart our Samsung washing machine. (I didn’t buy it) Dampers blew out. The damn thing was trying to beat itself to death.
Fortunately this turned out to be a known (as in class action) issue. $75 in parts a YouTube howto vid on the process and we’re good to go.
It just reinforced my Aversion to Samsung.
