"But, it's not my power that need concern you. Rather, it is the power of my disciple!"
As a reply of Korvac not fearing Strange's power does suggest Krugarr >> Strange at that point.
I'm talking about 616 Dr Strange, GOTG Strange wasn't as powerful as he was in his prime.
"He placed the infant in a realm that exists outside of physical space, Vance Astro. It is a dimension in which not even his power can function"
He explicitly mentions a specific realm/dimension that blocks his powers. It's on panel
After he invoked a spell which bound him.

Anyway it really doesn't matter as Monarch can easily BFR him to quantum realm which is outside physical universe too.
