That being said, the Samsung 8K TV models already have terrible power efficiency even without other issues coming in to play - I'm not sure whether it is to do with them having more FALD zones or just higher peak nits (or a combo of both) but the lowest efficiency rating their 4K QLED TVs have is B, whereas their 8K TV's can go as low as D (A being the best rating).
There's also the hybrid decoder recently committed for XB1 and later consoles using DX shaders and UWP, it would be interesting to see what the power consumption on the XSX doing 8k AV1 decode when using that.

TVs don't have the horsepower for SW decode in any case. The big power differential is with computers which can provide lots of peak compute in exchange for much more power draw. And we're talking 2022 before even half of new PCs have AV1 HW decode, and 2025+ before the installed based could be even 50%. YouTube using any codec that doesn't have a HW decoder on a system that does have some HW decoders must hugely add up. Plus the encoding power needed is also a lot higher.
The XSX decoder is probably better, but consoles are power beasts in general. Xbox and PS consoles generally draw >100 watts to just have something on the screen. Compare to things like Roku or Fire TV which draw <10 watts running full blast.
Of course, when doing streaming over 4/5G, higher bandwidths also mean more antenna power, so there's some tradeoff there somewhere.
Environmental organizations should really come out with a browser plugin to force YouTube et all to only stream the best codec that has a HW decoder.
