iOS 11 Nivagation bar sharp animation

Question

When I set the navigation bar property:

navigationController?.navigationBar.isTranslucent = false
navigationController?.navigationBar.prefersLargeTitles = true
navigationItem.largeTitleDisplayMode = .automatic

I observe sharp animation on scroll. I want animation exactly same as if this option is true. See pictures below.

Smooth (with isTranslucent = true)

Sharp (with isTranslucent = false)
