From NASA:

Fans of science in space now can experience fast-moving footage in even higher definition as NASA and ESA (European Space Agency) deliver the first 8K ultra high definition (UHD) video of astronauts living, working and conducting research from the International Space Station. The same engineers who sent high-definition (HD) cameras, 3D cameras, and a camera capable of recording 4K footage to the space station now have delivered a new camera capable of recording images with four times the resolution than previously offered.

The Helium 8K camera by RED, a digital cinema company, is capable of shooting at resolutions ranging from conventional HDTV up to 8K, specifically 8192 x 4320 pixels. By comparison, the average HD consumer television displays up to 1920 x 1080 pixels of resolution, and digital cinemas typically project in resolutions of 2K to 4K.

"This new footage showcases the story of human spaceflight in more vivid detail than ever before," said Dylan Mathis, communications manager for the International Space Station Program at NASA's Johnson Space Center in Houston. "The world of camera technology continues to progress, and seeing our planet in high fidelity is always welcome. We're excited to see what imagery comes down in the future."

takyon: Turksat recently tested 8K resolution satellite broadcasts:

Turksat has tested satellite broadcasts in 8K Ultra-HD, demonstrating the ability to transmit content with 16 times the resolution of HD. The practice broadcast showed scenes from Istanbul, Turkey, using the Türksat 4B satellite at 50 degrees East. Turksat said testing 8K at a time when such broadcasts are uncommon will give Turkish companies a leg up when competing globally in the future. Two Turkish companies, satellite broadcast hardware provider Kızıl Elektronik and TV manufacturer Vestel, partnered with Turksat on the test, along with Japanese chipmaker Socionext.

    Perhaps, but what really makes a difference for resolution is physical display size of the picture. For instance, a 480p picture just won't look good on a 32" TV no matter what. You really see a big difference between 480p and 720p on a 32" screen. There's much less difference between 720p and 1080p on that 32" screen. You start projecting a 720p image on a wall vs a 1080p image and you're going to start seeing a Major difference in quality.

    VR is trying to make an image look like it's a giant projection on a wall. So, much higher resolution will definitely make a difference, to a certain point. Maybe 8k is that point, but as takyon pointed out elsewhere, closer to 16k per eye is more likely.

    I remember the first time i played a videogame on a projector. I said "cool" for the first 10 seconds, then realized the scenery was too spread for the eye to catch everything fast. Of course the nature of the game matters a lot, a driving sim or a flying sim should be gorgeous.
    Worthy the investment? maybe in 10 years. Make it 20.
