Localizing app in google play - adding localized graphics

Hi everyone!

So I have my app in google play, I’ve already translated it and I saw that you can also add special screenshots, icon, and featured image for EVERY SINGLE language.

My question is if you think it’s effective for app store optimization? Can anyone share from his experience? I think I’ll just upload the icon and 2 wide images required, ignoring the 24 screenshots (8 screen shots for 3 android sizes=24).

Anyways, please please share your wisdom, I really appreciate it.
Thank you!
