All of the effects from Channel Destruction seems to be working for me. Maybe you're doing something wrong.

EDIT: Editing this to prove with screen shots.

You gain a 'Destruction Energy (Dragon)' status until your next turn, which increases your STR and WIL by 2 + 1 per 10 Scaled SAN.

This is with a Hyattr that has 20 SAN.
Without the buff:

With the buff:

If you use Flame Breath while you have this status, the width of the line is increased significantly, and will leave behind Cinders for 2 rounds that deal damage equal to 5 + half of your Scaled SAN.

It will also increase the damage of the skill by 100% of your Fire ATK.

Without Channel Destruction:
