Of course, the author’s main point, that 4K isn’t worth the additional fees most providers charge, is demonstrably true. However, there’s another factor the author didn’t mention: a 4K TV also adds high dynamic range (HDR), an improvement that definitely <i>is</i> noticeable regardless of one’s distance from the screen. Even “just” 1080p is pretty snappy when HDR is available. For example — and, yes, I know many HN commenters aren’t into sports, but just for the sake of the example — HDR makes a world of difference when you’re watching, say, a night game and can see a much more realistic range of brightnesses in uniforms, helmets, and even just stadium lighting in general. The same is true for watching 4K/HDR travel videos on YouTube.
