Correct. The current zero point energy is believed to be a false vacuum (local minimum). One of the end-of-the-universe scenarios involve it tunelling to a lower state (bubble nucleation). Things become progressively more dire the lower the energy of the next (false or real) vaccum is, including matter and gravity ceasing to exist. Not only does this sound a lot like "no information at absolute zero," it is also a terrifying existential crisis (you're welcome).
