Do DC pumps use less power as head pressure increases?

I know AC pumps use less power the more head pressure they have to deal with (or more correctly the less water they pump due to head pressure) but I'm wondering if anyone knows if DC pumps do the same thing?

I'm assuming the answer is no because they have a controller that determines how much power the pump will use, unlike AC pumps. But I'm wondering if anyone has done any actual testing or has any links to such data?

If the answer is indeed no for DC pumps then there's a good chance an AC pump would actually prove more efficient when dealing with lots of head pressure, like a basement sump for example.
