LTspice: reverse biased diode fails in ac analysis
You are conducting an .AC analysis, so you can't treat the results as if they were in .TRAN. In .TRAN, you see the direct effect of the applied voltage. In .AC, despite you applying a DC voltage, the result is the magnitude and phase of the applied AC 1 voltage.
What happens is the DC .op point is calculated (since this is a nonlinear element) based on the DC value, here 1 V. The diode is linearized for a small signal analysis. Then a 1 V complex signal is applied and read at node out, and the magnitude of it would be based on the resistive divider formed by the linearized resistance of the diode. Also, the default parameter for Rs is zero, which you haven't set.

Seeing you modified the question, I don't think it's possible, since the .AC analysis tries to linearize all the models, there is no dynamic value, and the signal is a complex signal.
