I've seen many people that chapter officially confirms that Enma is a power up but can we look back at chapter 955 the chapter which Enma is introduce and see if that's the case.
Enma's only confirmed power is forcibly draining the user haki known as ryou in Wano
So Enma doesnt actually have it's own "power" just draining Zoro's. Zoro must have meant that he needed to allow more of his haki to out as he was using to little before due to not wanting all his Haki drained.
Zoro is actually kinda of nerfed with Enma and Zoro himself admitted that he would get stronger ONLY WHEN HE GOT USED TO ENMA.
