Yes, this statement is true. In general, the robust standard errors are a
true indicator of the sample-to-sample variability of your parameter estimates
even in mis-specified models.
As for a reference, try
Domowitz & White (1982). Misspecified models with dependent observations.
Journal of Econometrics, 20, 35-58.
