No secondary bonus, but you cannot max out your stability bonus like you can a tech bonus, meaning, once you reach maximum land/naval/trade/infrastructure tech, the +5 is useless, but you will lose stability, and therefore still get the +5 bonus for fine art academies, right until the end of the game.
Look at it this way.
1. Most of the game time I spend at +3 stab. Certainly, I spend more years total at +3 stab than I spend with my tech maxed. This may just be my playing style, of course
2. As soon as my base trade or infrastructure hits 500 (and it will) one percent of that (refinery respectively goods mnf bonus) is 5d, which invested in stab is equivalent to the entire bonus for the Fine Arts Academy, but I also get the research. In other words, at 500+ a refinery/goods manufactory is equivalent to a Fine Arts Academy for stability purposes if you are always at low stab, but you also get the extra income when at max stab. And the research, of course. And the bonus scales with the size of your nation, rather than staying small and progressively insignificant.
3. Already when I reach 250 it pays as much towards stability as a Fine Arts Academy, assuming I stay at stab three at least for half of the time.
So unless you intend to stay with a small nation, a Fine Arts Academy just doesn't compare to those whose effectiveness scales with nation size, ie. refineries and goods manufactories.
I'll build one, for style, in my capital, and that's it.
