is it possible to change the theme but not the icons ? (on s7)

[Android Central Question]

I have an s7, I want to change the theme to dark to help saving the battery, but every theme I have tried adds frames to the icons on the home screen. I don't install lots of apps, including the defaults and without the hidden ones there are around 30 on the home screen, but often I can't see the app I'm looking for, even if it's one of those 30. The frames added by themes make the icons smaller and just unfamiliar. Any ideas? Thanks

Samsung Theme changer has the option to change icons. look for those
