I recently purchased some Cirrus basses that were made in 2017 and sealed in the box until now. One of the first things I noticed is that the strings still sounded excellent. OK, nobody has been playing them and getting oils on them but it's not exactly like being sealed individually in the pack either. The strings were still exposed to air and some humidity. Would non coated strings have fared as well? I don't have any comparable experience, so any conclusion on my part would just be a guess. I was strictly a Rotosound guy before and outside of trying Cold Steel strings when they first come out, never strayed from my trusty Swing Bass 66's. I couldn't get more than a month out them during the gigging days but they just had "that sound". The Dragon Skins don't sound as bright but only slightly less. Let's see how these sound after some actual use. My next set of strings may not be Rotosound.
