In order to fairly compare jpeg and RAW, you need to make processing adjustments to the jpeg file, just as you made adjustments to the RAW file above.

It is possible to adjust a jpeg file in post processing, just as it is with a RAW file. It is not fair to adjust only the RAW file and compare it to an unedited jpeg. There is shadow detail in the jpeg that can be retrieved with the use of the same adjustment slider you used for the RAW photo.

After you make that adjustment, a comparison of how much shadow detail was recovered from each format, and any noise issues can be fairly evaluated.
