coralline algae?

I know they aren’t the greatest pictures but wondering if this or coralline algae? Tank has been setup since Jan/Feb

Am I finally getting coralline?

Does this look like coralline algae to you guys? Tank is 10 months old and has been struggling with nuisance algae but recently I bought a ton of snails and they have worked like crazy on that rock. There is a snail shell my LFS gave me with coralline on it in the system as well.
