blackflame covenant Disciple of Varashta Sorceress interaction

So blackflame covenant changes all your fire spells to chaos with purple additions for visual clarity. sadly it doesnt change the Disciple of Varashta Sorceress spells even for the fire djinn. as far as i can tell the spells do still get converted to chaos but their visual effects dont reflect that and stay orange instead of purple.

can it be purple? <3
