My understanding is that the “super” in superdeterminism is just making clear that we are considering the experimenter completely determined as well, but yes, they are essentially the same thing.

Last paragraph I mean what you interpret — our everyday experience of “free will” may blind us to certain possibilities that we have no strong evidence for or against, just as our everyday experience of a classical world makes QM seem “weird” and unintuitive, even when the experimental evidence is well-established.

There’s a particular curiosity when the possibility of a world without free will calls into question the extent of the power of science itself. Are there other techniques that can provide satisfying arguments about the potential nature of reality in a world where we cannot rely on the power of experiment to reveal this nature?
