Those are computer-generated images, like you can make with AutoCAD or Solid Works.
If they had something real, I think they would be showing it, not some dumb CGI still shots.
The CIWS gun the system uses is very real and already deployed. The “new” part is the adding of six missiles to the CIWS mount.
As I said, the gun is very real - it appears at 1:02 in this video shot during Chinese war games back in 2013. It shows up a few times after that with more footage after 2:53.

They took the original Type 730 and converted it into a land CIWS system, like we did the CIWS Ashore program. They called it the LD-2000 system. Then they put six TY-90 missiles on it, called it the LD-2000 Gai and apparently had some success with it. They're now backporting the missile capability back to the parent Type 730 naval CIWS.
Here's pictures of the LD-2000 Gai in the metal:
These pictures date back to 2011 when the UAE expressed interest in buying some.
The Type-730 gun system has been in service for over a decade and the HQ-10 missile has been around for a few years and is being deployed on several Chinese ships.
And the Chinese have operated a similar Russian system called the Kashtan on their Sovremenny class destroyers for a decade now. Plenty of time to steal/copy the technology for an integral CIWS.
