In my next post, I will provide the solution to the quiz so that you have all the information you need at your disposal. In that post, I will also specify on what grounds I consider NR in RAW visually detectable in the images from the two cameras in the quiz that do it.

I lack time to attend that quiz, but I wonder if all chroma noise reduction has been disabled, or if the default value of 25 was used?!

As I have already pointed out twice in this thread: Yes, all NR is off. If you have the slightest familiarity with ACR/LR, you can see that without even having to ask. With chroma NR at default, you see hardly any chroma noise at all even at quite high ISOs.

There is a strange grid like pattern in the first image (and the second?), I know this one in a more distinct variant from raw converters that run their first quick pass before finishing the rendering/demosaicing of an image.

I don't know what you mean by "strange grid like pattern" nor what you mean by "the first image".
