Well not if the environments contain different versions for the same package. Like e.g. CairoMakie in the two environments you posted above. This currently is a fundamental limitation of Julia’s compilation process. I think there are ways to fix to fix this but I believe it is not currently a priority for the developers.
I don’t have a clear source on this handy. E.g. the Pkg.jl docs confirm this rught at the bottom of the page. Here is an older discourse thread about this question as well.
