Denoising high-ISO images: a sourdough bread

Since this thread takes a close look at denoise, I’ll bring up an issue I am seeing, but if you think I should make a new thread, I’ll do that.

The issue is that when I export this edit, there is noticeably more noise in the jpeg than in the image shown in dt.

I am using darktable-3.7.0+795~g0cae2c24d-win64.exe.

The posted jpeg is what you get with denoise on. If you turn off denoise and export, there is not much difference in noise. I have tested turning all other modules, except exposure, and they don’t change the increase in noise.
