On paper, the benefits of 8k over 4k are clear. But like the transition between 4k and 1080p, in practice, the difference isn't as noticeable as you might think. 8k TVs have 4 times as many pixels as their 4k counterparts and a shocking 16 times as many pixels as a 1080p TV. These extra pixels should make a significant difference in picture quality, but they're most noticeable if you're watching native 8k content and are sitting close enough to notice the difference.
