Hi, I saw that on (relatively) recent releases (DVD & BR) that some of the Classics (Ex.: Dumbo) had recently recovered theit original RKO logo in the feature (same for the shorts). But some still haven't (can't say for the BR): Bambi & Cinderella (among others).
Is it still the case on their BR release (Bambi & Cinderella) ? Aparently, they are on the laserdiscs, but cannot be confirmed (for Cinderella at least).
Here's a samble that somebody did post on Flickr:
