My 12 mini problem is a bit different, but I think gives hope that a software fix can be implemented.
Moved from iPhone 8, as soon as I restored from iCloud onto the mini, I noticed how much better the screen is on the 12. On the 8, I always had brightness at around 75%, with True Tone, Night Shift, and Auto Brightness all turned off.
Had the mini setup same way, brightness at maybe 65%. I then decided to go into settings on the mini and turn on Night Shift because my wife said it's good for my sleep. Had it setup to Scheduled at 10PM on and 7AM off, turned on Manually Enable Until Tomorrow, slider to Less Warm. Looked at it, didn't like it, went back to turn everything under Night Shift off.
The problem is, my 12 mini screen never went back to the fresh, crisp display it was prior to my Night Shift experiment.
After I turned Night Shift off, I went back to finishing setting up some other apps and I thought to myself that it looks different. The screen is noticeably dimmer and has the slight yellow tint. I spoke to Apple support and they had me check all the usual settings which I already have done. The Apple person sucked, by the way. I have afterwards gone through Reset All Settings but still haven't gotten the screen to look like before the Night Shift tryout. Moreover, it definitely gets worse in the evening.
All of this makes me think that there is a software bug of some sort that is connected to Night Shift. I had only started having issues immediately after I enabled Night Shift. It was an instant difference, and the timeframe between me enabling Night Shift and then disabling it was less than 5 minutes. It is as if disabling it didn't fully work, and Night Shift is still affecting my display.
