I think it is telling that even Hollywood is not yet on the 8K bandwagon; for example the ARRI Alexa LF camera mentioned in the article is "4.5K" and the Sony Venice is "6K"; I venture to guess that vast majority of feature films are produced at 4k currently. I find it unlikely that smartphone video footage would be at this point significantly improved by changing recording format to 8k.
