General Relativity describes gravity as the geometric result of space and time being the medium through which matter travels. Quantum Field Theory hasn't been able to describe gravity at the subatomic level though. So in conclusion I'd say we have no idea if the description of gravity we have using General Relativity is 'real' or just a really good prediction tool.

I'm also not really sure how we would differentiate between calling something reality and a perfectly predictive model.

I think you could say that most astronomers consider gravity geometry, not a force, but some physicists might not agree.
