You COMPLETELY missed the elephant in the room : 8K TVs have really, really massive CPUs that waste a TON of power (150-200w for the CPU, 300-400w for the TV, often!) Think 8 cores of the fastest arm 64-bit processors available plus extra hardware accelerators! They need this extra processing power to handle the 8K television load, such as upscaling and color transforms - which never happen when you are using them as a monitor!
So, 8K TVs are a big energy-suck! There's a reason why European regulations banned 100% of 8K TVs until the manufacturers undoubtedly paid for a loophole, and now 8K TVs in Europe are shipped in a super-power-saver mode where they consume just barely below the maximum standard amount of power (90w) ... but nobody leaves them in this mode because they look horrible and dim!
If everybody were to upgrade to an 8K TV tomorrow, then I think it would throw away all the progress we've made on Global Warming for the past 20 years ...
