Default Distortion through Early Effect - mainly low Order or high Order Components ?

Jim Early first characterized this effect due to an effective decrease in the base width by BjT's because of the widening of the base-collector depletion region, resulting in an increase in the collector current with an increase in the collector voltage.
What kind of distortions are to expect, if the Early effect is very strong (large values of early voltage VA) ?
Is it rather even-numbered or odd-harmonic?
so as more low order or high order distortions?
Thank you for your comments.

here some informations from Mr. James M. Early:

Mainly second harmonic, goes up with current a lot.
