Quantum immortality says something concretely different than what you're describing; it says that you always have a subjectively high probability of continued existence. By quantum immortality's reasoning, that is not the case under classical mechanics or non-Everettian quantum mechanics, where there are many situations where you have a conscious future with subjective probability of effectively zero. Of course I disagree with quantum immortality though I agree with Everett, and I think you are kind of restating my point: Finding outselves in the purple region is not surprising and is what we should expect. But quantum immortality as I believe it is usually stated does not require you to be ambivalent about non-existence like you say. It promises future existence, which I think is invalid.
