My experience is that, unlike PRIME, DeepPRIME leaves very little in the way of unwanted artifacts. The trick is to not make the settings too strong. I only apply it anywhere close to the default setting when the ISO is very high or the image is very underexposed. If I get unwanted artifacts, it’s probably the demosaic method DxO uses, in which case I have to use another program for RAW processing - which is fortunately rare for me.
