No, based on the aircraft shape displayed on the screen, it should be J-16.
Why? Because the MFD displayed an outline of an airframe that – to your eyes – resembled a J-16, so it has to mean that this MFD is adopted by the J-16? What if the outline was that of a F-15 Eagle, or one of a number of Western 4th-gen fighters that could fit the general contours of the graphic? Would that mean the MFD is installed on those fighters as well?So can we start assuming that the J-20 and J-16 use the same, if not very similar, MFDs in their respective cockpits?
What if the MFD had displayed the outline of a chicken with its wings spread out? What then would that mean to you?
Why are you getting so hung up on that graphic? It's just a demo graphic.
