“exist” is an interesting word, for something so difficult to define or detect. All of these arguments apply to “appearance of qualia” or “belief in qualia”, rather than to actual qualia. I don’t know how they wouldn’t apply to p-zombies.
I tend to think of the arguments about whether qualia (or consciousness or free will) exist as similar to a question as to whether topographic lines exist. They’re very useful on maps, they correspond in some ways with the territory (altitude, to a very coarse approximation) but they’re not ACTUALLY part of the territory.

There’s no difference between qualia and appearance of qualia. Note that qualia aren’t defined as non physical.
