I think “real” is a bit of a problem there because if vegan cheese is real it means it’s really vegan. I think the analog you’re looking for would be “fake vegan cheese”, or to make it less double-negativey we could just say “dairy cheese” which would be a perfectly understandable modifier on cheese just like how “vegan cheese” is a perfectly understandable modifier.
If vegan cheese is a problem i’d like to hear your take on “electric car”
