It looks to me that there might be markings around the aft elevator, but that could just be a difference in the sheen of the stain/paint due to the metal surround.
It's hard to tell on the early war carriers. I swore up and down for years that the Yorktown had no deck markings at Midway. The just don't show up in any of the photos. But when the F4F DVD came out last year, there's footage of Cheek's F4F landing onboard during Midway and flipping onto its back. And I'll be damned if you can't see white dashed line markings in that close-up footage of the deck. Too small to show up in photos (some even closer than the one you've posted above).
I'd guess that there was probably something there, but couldn't say what. I agree that the Doolittle lines should have been painted out by then, or at the very least worn away.
