I suppose that your premise
could be defended.
But I have never seen
any convincing
photo which would serve to prove it. Not a string of numbers - convincing photographic evidence - with a similar amount of processing applied to both the 'raw' and the 'jpeg'.
The comparisons seem virtually always to be with totally unPP'd jpegs, and heavily processed 'raws'. Usually the jpeg has had sufficient processing in-camera, and the 'raw has been PP'd a lot, and a tweak or two can bring the jpeg up to whatever superiority the 'raw' is supposed to show.
Essentially, the term "RAW" seems to be the factor which makes it desirable. People just like the
sound of it, seems to me from all the talk I've read about it over the years. Sort of like the call for "Complete camera control" from folks who don't know what "Aperture" is or why it (might) matter - and that's been seen often enough!
As far as I can see, 99% of the PP done to "raw" files is an attempt to replicate the JPEG which the camera's engineers have provided, and any improvements can very well be replicated by relatively simple PP work on the JPEG, if such difference be worth the bother.
There is supposedly a great improvement in highlight rendering. The 'multiply' function in PSE can and does make remarkable improvements in highlights whenever actually needed.
Of course, that's my "IMHO", obviously you don't agree or you wouldn't have started this thread.but, since
you brought the subject up, it's yours to prove.
It's essentially a matter of opinion; of detail.
And, if "better", it's not " 'Way More better"
