Sorry I'm late to the thread but I downloaded your shots and then had to run to an appointment.
Anyway, I opened them all in DPP 4 and they look pretty clean using it, even with the lighting conditions and zooming to 400%.
Here are a couple of jpg's zoomed to 100%, which are pretty small in width. All I did was adjust white balance. Other than that, it was in and out using DPP's "Convert and save" command. I did have to d/l your lens profile, but I let DPP adjust that (I used it's defaults) and the same with NR.
I ran this one through Topaz Sharpen because it has a tendency to reveal noise (using a very light setting). The only thing I saw were some hot pixels, which I've found to be common with my R cameras.
As you can see, these are pretty clean and typical of my R5, R6 cameras. Now, my R6 mark II takes it another notch 🙂
