I don’t know what I’m talking about. But, I recall the Unity3D folks talking about a camera calibration process that involved photographing a dozen full frame images of a flat neutral gray surface, averaging all those images to average out the sensor noise and being left with an image containing the per-pixel bias of that particular sensor.

This is called flat frame calibration, basically all cameras sold today will have that auto applied to your raw data even. I had to implement it here for processing raws from a very old camera: https://blog.maxg.io/reverse-engineering-the-sinar-ia-raw-fi...
