The best iPhone X raw denoise settlings in dxo photolab I found

I did a bunch of testing comparing all DxO deep prime settlings from the original denoise model to the newest xd2s and the best balance between noise/detail/artefacts can be achieved with the next settings :

DeepPrime XD Amount 20 Noise model -30 to -20 (-30 is cleaner, -20 is more details but also artefacts)

Next you need to bring the denoised linear raw to ACR or Lightroom and apply additionally manual luminance denoise amount 20-25 detail 100

With these settlings you can achieve an almost perfect naturally looking clean image that looks authentic compared to the noisy variant. You can’t get the same level of denoise with adobe denoise ai as it lacks fine tuning.
