This is great!
It's not going to work in real world situation.
Remember how blackmagic showed color match feature in resolve 12? And guess who's using it now? No one, because it doesn't work.
Nuke has ability to color match shots for years and it's still far from perfect. I bet that a company like Foundry could've come up with a better algorithm but there's too many variables come into play.
I'm curious to test it but at the same time I'm pretty skeptical.
