Profiled noise reduction adds green noise
When I use the profiled noise reduction module with my Sony RX-100 with the wavelet method, it reduces the noise very well. Except for the green channel, where it reduces the noise, but adds a lot of green noise at the same time. It happens especially in greenish areas and on high contrast edges.
Here is an example image as well as some screenshots. I tried it also with all modules disabled (except for profiled denoise) and it is the same result (except with disabled white balance module, where it is hard to notice).
