Denoise AI is fine (although the resulting files are rather huge compared to DXO or Topaz).
But I would like to preview the result in the before/after box without the coloured noise in the "before" display. Just as it occurs in the classic denoising effect.
By default the Raw image is already coloured denoised, why showing something that as already disapeared? Only luminance noise is required, precisely what we see before clicking on Denoise AI...
