It's true, TVs don't have the same experience the painting. However, they enable a lot of other abilities that let you experience art in a very different way.
With a 4K screen (even the super-cheap one I bought 3 years ago) and sufficient scanning resolution you can zoom in and see the paint clinging to individual fibers of canvas. You can achieve closeness and magnification far beyond what you can at an art museum. You'll never get that close to a real van Gogh, breathing on it and with a magnifying glass!
My thinking is education and exploration. There's a to be said for volume in art viewing too. With the TV+software experience, you can construct progressions of an artist's work, quickly build visual trees showing change and relationship of art genres. You can visualize the _genre_ and _time_ in a way few can at an art museum.
Also think about AR and VR experiences. In the light form, imagine watching curator talks when they can serve up high-resolution images and zoom in to specific features, or highlight and "pull out" sections side by side. Or superimpose their hands to visually guide your eye as it's discussed.
That's where I see the future of art in digital form: bringing it into the home and school, and augmenting the experience within the museum. TV brings vast scale and new presentation abilities, which I think will complement the power and complexity of individual static works.
Then, there is also the ability to deliver art that is not static, which I think will develop soon. Where the image itself slowly changes either by artistic effort (strictly dictated change) and algorithmic. I imagine a Kandinsky-like work that changes subtly over minutes, hours, or weeks.
I'm actually not a big art enthusiast myself. But it turns out I'm extremely passionate about art presentation and how access and exploration can be magnified.
Dang, now I want to pick this up again. I'd be interested in talking more, if you are. I love the subject.
