If it is an HDMI 2.0 port with HDCP 2.2 then the limitations are the same as those with an HDMI 1.4 port. HDCP 2.2 cripples the bandwidth available. Any HDMI 2.0 ports without HDCP 2.2 are full speed (18Gbps) and capable of full 4k 4:4:4 8bit. it gets more complicated when you move up to 10 bit etc.
