The short answer is no one knows for sure since there is no 4K Blu-ray standard nailed down not to mention there are no studio's signed up for content as the format doesn't exist as yet.
But, HDMI 2.0 unto itself is not enough. You're going to need HDMI 2.0 and
HDCP 2.2 with your equipment. Or at least that is the expectation.
If you bother to read the spec, you'll find it will be necessary (expected) to have an internet connection to play any 4K content from a disc. Your equipment will be checked via internet (phone home) to see if it is valid 4K equipment before keys will be passed to the equipment to allow 4K content access. That means the display, Blu-ray player, receiver, etc.; any thing that connects via HDMI to the source. This check can be preformed continuously and randomly to verify no corruption of the copy protection. Etc., etc., etc...
HDCP 2.2 is a clean sheet of paper and is not backward compatible. The HDMI 2.0 transmitter and receiver will however support older versions of HDCP for comparability of 1080 Blu-ray.
Since there is not a lot of equipment out there yet that supports both HDMI 2.0 and HDCP 2.2 it's possible what you've bought may or may not work with coming 4K Blu-ray. If it does work it is also possible that it may not be 100% compatible with a standard that does not yet exist.
