If the 34s still uses my Lambert's W code I can say that it usually gives 30+ digits, but not always all 34 can be considered correct. That's almost impossible with the same 34 digit working precision. ;-)

In this case the result you posted is less than 3 ULP off, so 33 out of 34 digits are correct.
