Shadow conjuration / evocation and illusion immunity

If a creature's stat block has

Immmune illusions

is it completely immune to these spells?

[Gauss]

Do you have a specific creature in mind?

My thought would be: no, treat it as if they automatically saved against the illusion side of the spell and suffer the quasi-real portion only.

Of course, it depends on the wording of the creature, it could be immunity to the school of illusion in which case, yes.

I have a player who reads rules questions, but here.

And alright; I suppose that makes sense. It hasn't come up yet but I expect it will before this combat is over.

If you look at the 'why' of the creature, it is blind. Creatures who are blind are immune to illusions. However, that does not make them immune to the quasi-real component of shadow conjuration/evocation.

I would say in this particular case it is not blanket immunity to the school but immunity due to being blind. However, it could easily be read as blanket immunity. It is a GM call.

I've been running it as blanket immunity, mostly because it itself seems to be a creature of illusion (+ dreams, given the dimension it comes from). I've seen other threads about vague illusion immunity wordings, though, so I know this is pretty uncertain footing.
