If you're further away than the "optimum" it's not a big deal, you just shouldn't be closer. And as the site explains, past a certain distance to the screen you can't distinguish between 4k and 1080p material (pixel wise).
If you wanna invest in a 4k screen, getting one with HDR capability is probably a good idea. But as far as I noticed the 4k market is quite chaotic currently since all companies try to establish proprietary standards and/or can't agree on a common one...
