I don't think it be a material difference. Although any potential visible benefit of >4:2:0 is going to be even smaller at 4K.

BTW. freesync and gsync screen work out of the box with pretty old hardware and even entry level screens have often support for it (mostly useless like TVs).
and player seem to support it too. a high end gaming PC is clearly not needed.

Well, that is cool. I will look more into it.

But the broader ecosystem challenge is that there are plenty of devices that can't play the content back, and not much content exists that could truly take advantage of a variable frame rate. Most titles that used sources with different frame rates had those assets conformed to the project's fps before editing. Getting end-to-end VFR working would require big overhauls to editing and content creation software upstream and then a new generation of content using those technologies.

Still, it'd make it possible to have the 48p versions of The Hobbit movies work on home video, which hasn't been possible to date as 48 fps support is far from universal, and isn't a broadcast or HDMI standard.
