Denoise-AI vs [embedded] AI-Clear

Is there a known explanation for these example results? ie DeNoise is trounced by AI-Clear

Are you using auto for both?

Auto-setting actually reduces the noise slider (see attached) and subsequent processing has almost zero effect. Oddly, increasing the noise slider significantly (the original post above) has almost zero effect as well. It’s not clear that DeNoise mode is making any change in the result at all (which would seem to be not working as designed). Particularly when compared to AI-Clear mode where NR is clearly obvious.
