The white was known as counter-shading, and wasn't disallowed for Measure 21, but it also wasn't used with it much. It was much more of a part of the dazzle schemes. Franklin's Measure 21 didn't have it based on the post-fire photos we have access to on
her Navsource page like
this one.
At the time of her catastrophic fire, she was primarily a Corsair carrier (68) and they and her small contingent of Hellcats (four night fighters and two photo birds) were all Glossy Sea Blue. Carrier Group Five also had 15 SB2C-4Es and 15 TBM-3s. I've seen both in tri-color and glossy sea blue and don't have any definitive photos for Franklin's aircraft, so I can't help you there at this point.
*Edit* Deck Blue would have been used on thinks like calwalk platforms, the tops of the Mk37 directors and 5" gun houses, etc. I've seen it used on the top of 5" gun barrels but only when the side of the ship and barrels was a lighter color such as Ocean or Haze Gray. Not enough difference to care with Navy Blue.
