The drawing I found on Profile Morskie 019 on Marseillaise & Georges Leygues has the latter painted in ms. 22 with an overall blue deck. Wood planking was, according to that drawing, painted over.
This makes sense to me: the ship was refitted into a US yard and if the workers were asked to paint that thing in ms. 22, and ms. 22 stated all horizontal surfaces to be painted deck blue, well, they had to comply
