"Like sorties, sparkly depends on whether a ship is MVP or performed a critical hit. However, unlike sorties, there's a chance that all participating ships will get sparkly when getting an S rating."

There's actually a math to it, not just chance. See Morale/Fatigue page, there is a table there that privdes effects of some actions to ship morale.

If all your ships participated the battle with 49 morale, getting an S rank will surely make everyone sparkly, because of the +1 and no deduction from returning from PVP.

if they started lower, ofc they won't unless she was an MVP or a flagship that barely made it to 50 morale.
