Certainly. And for small perturbations it would be linear; just in different proportions depending on the perturbation vector.
How this proportion varies by perturbation vector direction I have no idea. Note that since chi-squared variance is 2 * DOF, perturbation squared magnitude (actually a re-scaled chi-squared with mean 1) variance is thus 2/DOF giving a standard deviation of about 0.12.
