6K and 8K is great for editing, just like how 96 KHz 32+ bit and above is great for editing. But it’s meaningless for watching and listening (especially for audio, you can’t hear the difference above 44khz 16 bit). When editing you’ll often stack up small artifacts, which can be audible or visible if editing at the final resolution but easy to smooth over if you’re editing at higher resolutions.
The same argument goes for audio too.
