That Render is for the star wars falcon cockpit not ESB and ROTJ and it's also not in the same aspect ratio as the film is in. nor does it have the same FOV settings as the lens that filmed the scene. But I would say that the shot that you pointed out is not the closest to the one in question in the film. It's this one.

yes it is looking to the left a bit but not enough to obscure the mandible if it were centered. Also take into account the height gain to actually frame the cockpit bars in such a way so as they would fill the screen without the dashboard visible. (This would obscure the mandible further) and in this case a fair tilt upward. Scroll up to the Route 66 mock up where the falcon visited Area 51 for a tourist trip to view the drop down of angle shift and how the flat face would be more obscured, and when centered the mandible would do a shift to the left further outward along the horizontal plane.

I really don't mind if it's not visible but my gut tells me that everything points to it being visible at that particular angle in the POV shot we see in the film. And only the shot I have pointed out. Please note I have disregarded every other angle as saying "No Chance". I am happy to put my hands up and say "you know what you are right"... But I still am not ready to do so at this time based on the evidence

That Line is very important Imp Fighter in ascertaining the actual horizontal face of the mandible indeed. But as I have stated earlier we also have to take in to account the height of the camera and the slight tilt downward but over the dashboard controls. The mandible sticks out in front of the Falcon cockpit at about 5 x length of the cockpit in to the distance albeit angled away to the left.
