Here's the thing:
Organic dyes are photosensitive. Inorganic dyes are not transparent, so they have
to use organic dyes, which come from plants mostly. The chemicals in the dye react to light. This is especially so with certain shades of blue.
There's no way around this, it's been the case forever, and it isn't
This is why from the very beginning PRS has stated the warranty doesn't cover fading. If people don't want to see fading, case the guitars when not in use. I've never had a blue one fade (though it's not why I case them).
As to the finish issues, all the poly finishes had them occasionally through the years. I had one long before V12 where the edge of the fretboard flaked. PRS took care of it, and it was one of my best-ever, long term guitars.
As with any finish, one can argue pros and cons, but for me, the nitro finished guitars have sounded better; my first nitro finish PRS electric was 2014. I find it makes a difference, and am awfully glad PRS switched to it.
However, the important thing is, while the guitars are beautiful to be sure, their purpose is 'musical instrument'. At that task, they've gotten better and better, at least for me. Call me a homer if you must!
