What is the difference between the pulse diagram of stochastic simulation and that of perfect foresight simulation?

Have a look at

Stoch_simull(order=1) and news shocks

Dear all, I have a stupid and embarrassing question to ask. I let dynare solve my DSGE model by choosing a first order Taylor approximation (i.e. stoch_simull(order=1,…) ). However, we know that 1st order linearizations yield the certainty equivalence property. Since my model contains news shocks, is there a conflict regarding the approximation number? As we know it is quite complicated to introduce news shocks into perfect foresight models. Many thanks in advance for your help. Best Robert
