Ghostrideryes it will, I'm using it right now with my MBP 15" 2017 through usb-c thunderbolt 3 cable or you can use usb-c to hdmi 2.0 adapter (I've tried belkin adapter) and you will get 4K/60hz.
kartiksathappanI'm running macOS high sierra so scaling my display doesn't show the exact resolution in system preferences. It only shows if you want larger text or more space under scaled option. Yet, when try to play around with this option then went to check the resolution in system report I can confirm it changes.
