Revisiting this issue with the camera core, it resembles what I saw when a cooled cameras fpa became detached from the 'cold finger'. I have to wonder whether the microbolometer die in your core has become in some way detached from the peltier temerature stabiliser on which it is normally mounted. The stabiliser creates the correct working temperature for the die and any loss of the thermal bond between the two will create a thermal gradient across the die. The item that is loose within the microbolometer module could be either the ceramic cement used to mount the peltier elements to the die or even part of the peltier element that was damaged by physical shock. This is all conjecture on my part though and sadly the only easy way to determine the situation inside the module is to open it and carry out an autopsy. Such will destroy the microbolomter module.

After some digging, I strongly believe that it's actually a ULIS UL 03 08 1 microbolometer, as indicated by the photos. I've found technical documentation for another ULIS model which appears to share the same pinout (UL 01 01 E), but the documentation for this model is behind a Baidu paywall.

The physical package is the same but you are likely to find some small electrical and pinout differences as it is a different 'series' of ROIC.
I would suggest measuring each pin, if it matches your 0101 datasheet that is OK, but if not then it probably is a pinout change rather than a camera fault.
Data for the 160x120 0205 might be helpful electrically.
