We will discuss the degeneracies between dynamical dark energy, dark matter and curvature in a non-parametric and non-perturbative approach. We highlight how incorrect assumptions about the flatness or matter content of the Universe can lead to inferred dark energy models with spurious dynamics, and underline the importance of using unbiased estimators for cosmological parameter estimation.
