It appears that when previewing adjustments in PureRaw 6, colors are desaturated and changed somewhat. It makes it seem as though the result will be worse than it is. However, the final output is just fine.
Here is an image of the preview of the original image in PureRaw:
Here is what it looks like with adjustments applied. If you look at the text, the red is noticeably dulled and darkened. I did forget to disable adjustments with these first two images, however it remains this way even with all adjustments disabled, and no matter what the denoising configuration is.
I do expect this is a side effect of perhaps a lower quality version of the image being used to generate the previews, to save on processing time, but it’s something to be made aware of. My two cents is that it would probably be best to keep color information the same in the preview, or make it configurable (similar to the “instant preview” setting), as it’s quite important and leads to misleading results when adjusting settings.
PureRAW is about optical corrections and denoising. Any colour that it shows is irrelevant somehow, after all, it’s meant to be a pre-processor or plugin for whatever app is dealing with PR’s output.
Correct colour? Does not exist by itself but by our expectations, baselines, requirements etc. Make it “right” with your favourite app.
Previews often cut short of a few things for the sake of speed. Whether the different colours are caused by design or a bug is something we can’t really say if nothing is written about it in public documentations.
Assuming it to be a bug, the best way to reach DxO support is by opening a ticket. Response can be slow and/or strange, but input isn’t simply dropped as far as I can see.
