I highly highly doubt this is a live video feed. Everything else surrounding this (including the building and all the other seats next to it) looks like flight simulation of some sort. Which means the object in the upper screen is a CGI.Then there is the portion underneath the center screen:

This guy is sitting inside a cubicle that looks like a cockpit mockup of a fighter jet towards the front. Notice another screen right in front of him (which looks like it is also displaying the cockpit view of the testbed plane itself, with the canopy frame partially visible), the throttle lever to the left, and the side stick to the right.
So, I think the 6th-generation fighter shown on the center screen very likely a CGI indeed.
Or (a huge) maybe, a live video feed from a chase plane that is flying alongside the actual testbed plane, but I don't think this case is likely.
Just my guess, but the thing in your circle is an aerial refueling probe.
Also, based on the giant projection in the background, the image of the large curved cockpit display looks to be inside the spherical simulator in the middle of the building.
