> "You don't need to film in 4K if you don't have a 4K screen!"

Besides the obvious fact that one might own a 4K screen in future, 4K (2160p) looks better than Full HD (1080p) on a 1600×900 "HD+" screen! It looks pure and clear thanks to higher bitrate and chroma subsampling.

What? You didn't know almost all consumer video cameras, including smartphones, record with 4:2:0 chroma subsampling, meaning 1080p video only has 540p of colour information? It has 1080p of luminance, but not 1080p of colour.
