I don't agree here. I base this not only on my own 8K viewing experience, but on
a double-blind study carried out by Pixar, Amazon, LG, ASC and Warner Bros on a 85' LG 8k OLED.
Truth of the matter is 8K is a waste of resources. You need a very large TV to see a difference and the vast majority of people will never have that size in their own house to begin with. The same goes for gaming. There are many reasons why TV manufactures push for this. First off, It's much easier (cheaper too) to increase pixel density than it is to improve overall picture quality. Secondly, manufactures are always looking for the next hot thing to sell to consumers. More K's people! Third, many manufactures are trying to differentiate between their lower-end and higher-end models, so what better way than to have an absurdly expensive 8K set. Korean and Japanese manufactures in particular know how close the Chinese are in terms of price to performance value. They need 8K to justify those higher prices. Doesn't matter anyway since Chinese manufactures are already in the 8K game. Expect QD-OLED to be the sexy -and expensive as hell- new tech in the near future. Possibly QNED too.
Also, picture quality, in it's current state, takes a hit due to the incredibly high pixel density of 8K. You need to push more light through an 8K panel versus 4K. That means an increase in power consumption and heat. Not to mention a much more powerful processor to upscale content that may never arrive.
