Dark for my new ZWO 1600, WHATS WRONG??

Description

Hi, I did get a replacement ZWO 1600 Pro mono today. Is started to test with taking some darks. The darks are 300sec. Gain 300 Offset 50. The camera is not attached to the telescope it is covered by cap and aluminium foil so no stay lights will reach the sensor.. Could please someone help me to explain the "star" with the surrounding ring in the left bottom part of the image. For me this does not look good.

I think it obvious that it is the camera that has a "defect". For me it looks that it is an area of hot pixels that is the actual spot while the surrounding ring is caused by the light from the spot being reflected back form the sensor glass. I assume that this is a defect that can not be compensated during calibration because it will instead of event out add "artifact".
