Only one of these art TVs actually fooled me into thinking it was a painting

I own three art TVs, and only one of them genuinely passes for a painting when I walk into the room. There’s a 32-inch Samsung Frame above a desk in our basement guest room, a 55-inch Frame over my office desk, and a 65-inch Hisense CanvasTV on the main wall of that same guest room. Most guests read all three as real artwork at a glance. I look at every one of them daily, though, which makes me a far tougher audience. After picking the Hisense over Samsung, I worked out why it fools me when the others only fool visitors. The answer has nothing to do with the wooden frame or the art library. It comes down to the screen finish.
