I just tried DxO Pure RAW. Great idea. One thing that bothers me - the automatic vignetting correction. It blows or saturates highlights away from the center. Make it selectable, please.
I understand that NR could depend on the vignetting correction. Then a few options, like 0, 25, 50, 75 or 100% would be great. I never apply 100% correction on my images.
Vignette correction in Photolab (and I think in Pure Raw as well) can cause issues. When I process my astrophotography images with DXO Photolab I always turn off the vignette correction because it causes banding issues, see Vignetting filter causing banding - #24 by LexB
I don’t know if DXO will change the options for Pure RAW, but if you want to have control you could switch to use Photolab.
