I found even with a shot taken with my ASI2600 (Which has a smooth noise profile and in this case a pretty decent SNR) that the AI sharpen seems to produce "Detail" that I am pretty sure does not exist, and a very odd looking "Elephant skin" background (To pinch a term from the car industry for a dashboard surface treatment that was popular for a little while in the 90s)
Denoise AI seemed to do better, but I still struggled to make it produce something that looked better than the original input straight out of Astro Pixel Processor, with a million and one ways to make it look worse.
