Darktable does not support DeepPRIME XD3, as this proprietary AI technology is exclusive to DxO's software suite, specifically PureRAW 6 and PhotoLab 9.6.
Darktable includes its own built-in AI-powered RAW denoise tool, but independent comparisons indicate it retains less fine detail than DxO’s DeepPRIME XD3, particularly in high-ISO shots and on fine textures like feathers. Additionally, Darktable cannot open the High-Fidelity Compressed DNGs generated by PureRAW 6, which use a compression format not yet supported by open-source editors.
