I do digital signage as part of my job. We use Samsung TVs. They do work better, but they do run hotter. Much hotter. We use Yodeck Raspberry Pi players (4K) using HDMI, Ethernet. ADA now says TVs in public places have to be very close to the wall. This means that the players have to sit atop the TV, either in the small gap between the TV and wall or hook & loop to the TV. The older TVs (we replaced them this year) were OK. The new ones, because they run hotter, melted the glue off the back of the hook & loop and let the player slide down.

I don't own one, I looked into it the last time I purchased a TV and just couldn't justify the price over the sale price of a regular "smart" TV. The more feature rich digital signage (from Samsung at least) with HDR10+, HDMI CEC, etc. is much more expensive than a consumer TV, i think 3-4x. It didn't fit my valuation so I just have a normal Samsung TV with no networking configured.

There are Samsung ones that are 4-5x more expensive with more features (HDR 10+, HDMI CEC, etc.) so its definitely important to make sure they have all the features you want. As with anything it may or may not fit your use-case
