I also get good results in this mode. For high ISO shots I usually start with a little raw denoise (0,005). Then two denoise profiled like described by Guillermo. For fine tuning I try these options: Lowpass filter: radius 3 (or 4.5 for very high noise) gaussian contrast 0 brightness 0 saturation 1 blend: color the lowpass trick also for low noise shots with only a hint of chroma noise. For very high ISO I found out that ca correction and/or defringe can remove some remaining color halos/speckles (but may also alter important colors). In general I try to use a lightness parametric mask to apply stronger denoise on the darker parts on the image. Then add a little vibrance/saturation to recover the lost saturation. You can save all this in a style to make it easier to apply. See attached xmp file.
