Does everyone else's company have confidential projects with the consulting firm and client logos splashed on seemingly every deliverable?

Worked in consulting for a while, now I'm consulting-adjacent, but this has been bugging me for years. Seemingly every confidential project/deal/etc I've worked on, no matter the depth of the NDA I had to sign, insistence we don't refer to even the client industry, only use the code name even with our managers, etc., every single PPT deliverable was done in the clients colors with both of our logos on every single slide. Word Docs often had both logos prominently at the top. Heck, a couple even had custom Teams backgrounds made.

Am I crazy in thinking these projects should be the exact opposite? PPTs that only use the code name, formatted with either the consulting firm's color scheme or a generic one, no Teams backgrounds, etc.
