Changing/reverting Samsung's "Recent tabs" color theme to Nougat (based on app's theme) on Oreo device

On Samsung devices running on Android 7.0 Nougat, the recent tabs have different colors based on the apps' theme. On Android 8.0 Oreo, they are all the same color.

I want to find a way to revert to the Nougat version. I plan to install Magisk, but rootless solutions are preferred.
