I do not think most things are "theoretically knowable", since knowledge is comprised of finite concepts conjoined in finite ways; and most of reality is uncomputable. You cannot know the state of the climate, even in principle. This is what the commenter was alluding to when they said, > there is some information-theoretic barrier for us to understand So the commenter can both maintain there are theoretical barriers to the possibility of all kinds of knowledge, which is outside of "knowable physics" without having any sort of dualistic view that this unknownable stuff is immaterial. So to be "outside of physics" is not coextensive with being "immaterial". You might have meant that, but it is this very conflation which has to be undone to understand OP's point
