probably not. I've had a lot of fun fiddling with kosher and sea salts of multiple 'flavors' recently.
per weight measure (_not_ per volume) sodium chloride is sodium chloride - NaCL - same number of molecules of NaCl per gram as every 'form' of salt. that said,
here's what I concluded, your mileage may vary....
all of the 'sea salts' - an all encompassing term for expensive stuff - have much larger crystals than table or kosher salt. as a result, the "salt" does not so readily dissolve 'into the food' - except for essentially liquid mediums.
the result of 'not dissolving so readily' is that sea salt sprinkled on / mixed into <whatever> is chunkettes / little nuggets of pure salt in the food as delivered to your mouth. chew chew, crunch crunch, oh my gosh - what's this - I've got a mouthful of pure salt....
more directly, I can understand how undissolved sea salt crunchies in a dough would indeed produce a "too salty" reaction. the same number of salt molecules dispersed evenly throughout the bread/roll would probably not be an issue; remaining in a concentrated crunchy salt nuggette, could be - "salt" is a very strong/primary taste bud function.
