Then you're not looking hard enough.
What is the black line extending from the outboard opening of the wheel-well that extends from the forward corner of the wheel well along the bottom surface of the wing, around the leading edge of the wing and over the upper surface of the wing if not a seam?
The fact that they are masking the landing gear from view is a tip off that theirs is a fake. The landing gear would give away a fake.
Good eyes, that appears to be an assembly seam, outboard of the wheel wells. The Iranians copied that seam but covering it with putty or duct tape, per the video, is just comical.
If they had the real deal the seam would be flawless like the photo.
BTW, look at the width of the aileron on the trailing edge of the wing. Compare that with the size and location of the ailerons on the video fake.
