I think there are two separate issues at play.
Clearly there is an AutoMask issue.
Also, I think there are combinations of avoidable and unavoidable underexposure.
It's possible the latter makes the former more serious. ...snip...
Yes, I think high ISO and low S/N makes the AutoMask more problematic.
Yes, you are certainly right to use settings that will improve S/N. In this case, I had what I had for files to work with.
Yes, the example here has avoidable underexposure. Could have been shot at 1/50th. Should have. Would have helped.
But, I get a pretty good image at ISO 4000, 8000 and sometimes more with today's cameras. That's what surprised me so much about the awful artifacts in the first image #1 above. It should have been OK, maybe not great, but OK. That led to the sleuthing. AutoMask and the "Camera Muted" profile turned a usable image into junk.
OK, I'll modify my conclusions:
- Try to shoot with settings that keep ISO down and S/N up.
- Check for unexpected results with Camera Profiles. The orange smear in #1 above.
- Be careful with AutoMask, it can leave tiny areas unselected on a textured area (e.g. a face), especially at high ISO
- In Lightroom, the Adjustment Brush is applied first, and then global image adjustments. That can make a difference.

A useful summary and important advice!
PS Being able to get the most of the raw files we have is a critical skill. The strategies will vary since circumstances vary. I often struggle. I guess it's like printing a difficult negative.
