Therefore, 8K TVs are available from the higher screen size that is starting from 55-inches.

Viewing DistanceNeed to sit closer to the TV, then only the human eye can see the advantages of 4K content.

The viewing distance can be from 3.3 feet and higher.

The larger the screen size viewing distance could be higher. Refer to the link to check the required viewing distance of different screen sizes.
Need to sit extremely closer to the TV, then only humans can see the difference between 4K and 8K content.  

The approximate distance is between 3 to 3.5 feet for a 55-inch TV.

Sitting too close to the TV will not be comfortable for people.

To avoid sitting too close to the TV, you can opt for bigger screens, but can’t think about the prices of 8K bigger TVs, it will be more costly.

OTT Contents4K contents are available on all popular OTT platforms.

Below offer 4K contents, Netflix
Amazon Prime Video
Disney Hot star
Currently, YouTube alone has 8K contents, which are limited to demo footage of travels and landscapes.  

Other OTT platforms like Netflix, Amazon Prime Video don’t have 8K contents.  
MoviesStill, the film industry shoots the movies under 2K resolutions, because of the movie theatre’s capability to project it. Therefore, no movies are filmed in 4K.   So, for movie lovers HD will be sufficient, but 4K will be the best option with upscaling. We have to wait long years to get 8K movie content.
GamingA large number of 4K games are available in the market.You need to wait some years to get 8K games.

But we might expect this a little quicker than 8K films.  

8K games should depend on the latest, powerful hardware.

HDMI 2.0 supports 4K contents at 60fps.

For 4K 120fps content transfer needs HDMI 2.1.  

Note: Latest 4K TVs come with HDMI 2.1 port.

I believe you have ended with the same conclusion that I’m going to say. Yes, in the battle between 4K and 8K TV, the winner is 4K TV at least for the next few years. There is no doubt, you can’t spend money on expensive 8K TVs unless you have many 8K contents to watch. Therefore, the lack of 8K contents is the main reason I suggest not going with 8K TVs now.  Also, it is newer technology there are no proven metrics about the lifetime of 8K TVs.

Considering the facts like expensive, lack of content, unsupported on OTT platforms, closer viewing distance to get the 8K advantage, and screen size availability, 8K TVs are not a good option or not worth buying now and at least for the next 3 years.  Go with 4K TVs this will never disappoint you, 4K itself offers better content.
