If there are some units with this problem and others that don't (haven't seen a non affected unit myself) , then it is impossible to fix it with firmware. That would also affect the units that work ok. I have asked on the official DJI forum a comment from DJI, but it has been dead silent. I think that tells it all. It is a hardware issue and they don't want to comment it.That’s not the case in a raw image (dng). With my m2 pro and mini 2 I have not such issues in raw images. They need to fix it asap.
