You could buy a roll of vinyl?
I don't know how much you'd want to invest in this but have you considered matte black adhesive vinyl. I honestly can't vouch as to how well it would work for your needs but I have used it with good results on tables.
It should peel off of the walls when you are done with it. Just an idea, I understand it could be pretty costly for some especially depending on room size. There should be multiple bulk sellers for items like Oracal 631 if you are interested.
