Does anyone know how to achieve this effect?

I'm not aware if there is an easier solution but my approach would be using something like https://github.com/Kureev/react-native-blur
What you can do is have a normal view in place of your current icon
This view will have a blur view and an icon with absolute position on top of it. You can toggle the visibility of the blur view based on the selected tab and that should achieve the result you want.
