J-16D with a new ARM?

This picture looks like a CGI. Are we sure the original image is real to begin with? I can't see how someone would have gotten an angle of those aircraft from that angle, and there are various details that make it look CGI (control surfaces, details on the airframe).
Not to mention if this was a real image I feel like we would have gotten other angles of it first.
Edit: the J-20s in that image have round LERX, which was only present on the original J-20 200x tech demo airframes. So that should confirm it isn't real.
That user also does not have a good track record of posting good quality/reliable imagery
