D750 issues - semi circle in the images

Hi,

My D750 went for a service with the known flare issue. Recently I noticed the a semi circle (or arc) on the right side of the images, and it is especially visible on a bright contrasting background and on larger aperture openings from 2.8..till f 16 or so. I did not check it with 1.4 (on 85mm..but I assume I can see the same).

I tried on Sigma 70-200 f/2.8, nikkor 24-120 f/4.0. I did try the same lens on a different D750 and I don't see any such issues there (to eliminate lens issue) and also I tried to view the images (SD card) on a different D750 (to eliminate screen issues)  and I saw the same arc issue...and which shows clearly that my D750 has some issues.

Any idea on whats the issue?

Circle wont be visible (for a naked eye) on low light situations and so I have attached one here(the last one).

Pls let me know if I need to contact Nikon.

Pls notice the arc between the right most coconut trees.

Intentionally under exposed to see the issue

This pic I took the very next day..early morning.

Nikon D750
