color pixel artefacts with profiled denoise and blend mode HSV-Lightness
I see weird colored pixel when using profiled denoise and blend mode HSV-Lightness. The issue happens with non-local means as well as with wavelet. Using blend mode Lightness instead is fine. I have attached a screenshot of DT, the exported JPG, the raw and the xmp file.
I am using DT 2.4.0 on Manjaro Linux.

According to https://www.darktable.org/usermanual/en/blending_operators.html, "HSV lightness ... In contrast to blend mode “lightness” this mode does not involve clamping."
Might be bad noiseprofile fit?
