It depends what you mean by "is real". Of course in some sense it is still real, just like triangles are real. But it's not real in the same sense that rivers or rocks are real.
The relevance in this context is that it gets rid of some privileged position for consciousness. If this explanation I gave were true (I have no reason to believe it is!), then there is no problem in reconciling qualia with materialism. Qualia are just an aspect of the modeled "I", not a raw experience that can't be explained. P-zombies are all that exists.

Rivers and rocks are less real than consciousness. Our minds can work with mental objects only, these objects often are built as an images of something outside of our minds. Most of the time images have nothing in common with underlying reality of an imaged phenomenon: for example we need to remind ourselves that you cannot cross the same river twice, because our model is a static object, while really a river is a dynamic process of H2O molecules falling out of sky and then rolling down to an ocean.
But our consciousness is the model of ourselves. The object (me) and its model (me consciousness) are much closer, there is no long chain of causes-effects passing information from external river to neurons. And moreover consciousness is a pure magic among other images: I can believe as hard as I can that river must be made of milk, and it will not change the river. But if I believe something about myself, it leads to real changes. Doesn't it mean that "I" is more real than any river?
Or... scratch that. I can agree with you we have confused naive understanding of consciousness mixing causes and effects. But I'm not sure that the rest is as simple as you describe. I'm sure a dualist will find a way to explain qualia as something that can't be reproduced in AI.
These things are never easy and they never have a definite answer.
