Is there a difference actually seen by viewers between the 8K image and the 4K image?
In one of the topics addressed at the "8K Display Summit" event, which took place on June 11, 2019 in New York, a series of conclusions were presented about the difference actually seen by viewers when it comes to native 8K content, compared to 4K.

" Much of the critical feedback so far about 8K has highlighted viewers' inability to see additional pixels, compared to 4K, when viewed from a typical 2.5 - 3 meter distance. This rating is based on standard measurement of visual acuity - more precisely, how well we see based on Snellen measurements The argument is that the pixels in an 8K TV are so close that they cannot be distinguished from a certain distance, while the scientific argument behind this conclusion is strong. , human vision is far more complex than simple acuity measurements might suggest.The reality is that you can see on the television the difference between a 4K and 8K image", the representatives of Display Daily explained, who mentioned that 8K technology offers a total image improvement of 35% compared to 4K, a 30% improvement in image quality and a 30% improvement in image depth. "Two recent studies have confirmed these improvements in perception when looking at an 8K TV, compared to a 4K TV. In one of these studies, conducted at a university in Seoul, 4K and 8K 65-inch TVs were installed and calibrated at a luminance peak of 500 nits. Viewers have been tested in advance to confirm that they have the right acuity and full color perception. All 120 viewers sat at 2.75 meters of screens in a darkened room - typical conditions for watching TV at night. The participants were shown on the same screen 16 photos and 3 videos presenting a wide range of images, and the conclusions were those mentioned above"was explained in the speech of the representatives of Display Daily. Inevitably, the above arguments are not currently sufficient to combat the unavailability of native 8K content, but this deficiency was valid 5 years ago and for native content. 4K. "Today there is a decent amount of native 4K HDR content available and I think 8K content will be produced and content at a similar pace in the coming years. Japan has already broadcast 8K content on a satellite channel and is preparing to broadcast the Tokyo 2020 Summer Olympics in 8K. It is a start, many other important sporting events will be broadcast in 8K. China will be a major market for 8K TVs, so content creation is expected to expand there as well as in Korea. In Europe, Rakuten from Spain has already announced the upcoming launch of the first 8K streaming service. Streaming service providers have contributed to the adoption of 4K technology and I expect them to contribute to the spread of 8K technology as well. None of the major streaming platforms has yet made public announcements about offering 8K content, but by introducing improved compression technologies over the next 2 years, allowing 8K streaming at an acceptable bitrate, you will be surprised to see these companies struggling to be leaders in 8K streaming. Sony also announced that the next PlayStation console, PS5, likely to launch in 2020, will be capable of 8K resolutions. All these pieces come together as one puzzle to drive the creation of 8K content, starting in 2020. The reality is that almost all content currently produced is in 4K or 2K resolutions, but that's not a problem. The new 8K TVs use very powerful upscaling algorithms, which creates an image that has more pixels than the received image. Upscaling has been used for decades in all types of devices where the input resolution of the image was lower than the resolution of the display. But this term is now outdated, because upscaling algorithms are now much more sophisticated. Perhaps a more appropriate term for this technical procedure would be image restoration", the representatives of Display Daily explained, however, who accepted that 8K technology will be adopted at a much slower pace than 4K technology.
