That is probably the *best* answer.  To compare user 1:1 for raw and jpg. 
I raised the raw to 1:1 because the noise was not very visible at lower
resolutions.  But to compare, both images would need to be presented
similarly.  And iiuc all images in lighttable view are thumbnails.

btw, I am not a developer, only a happy user.  Better answers may be found
on irc at #darktable.
