Digital BW, The Print

I have just printed out the 729 patch ProfilerPRO targets on these two
papers and they printed IDENTICAL to my eye. What is the likelihood that
the BC Eclipse Satin is at least coated with the same inkjet receiving
layer as the Photo Rag? Is it likely that BC Satine is made by Hahnemule
as well?
I am thinking that I may only need to have a profile made for one and it
will print identical on the other. Has anyone had both papers profiled
with Generations ink and what were the results?
