This information applies to all versions
DNGs exported from DxO PureRAW are linear DNGs, which means they are already demosaiced. Therefore, in DxO PhotoLab, they show the "no module available" icon and the tooltip says "some corrections are not available with linear DNGs." However, this is not an issue as those corrections have already been applied to the file. If necessary to change the corrections, please go back to the original RAW file and either use DxO PureRAW or DxO PhotoLab.
