S8 Ultra What's the hack or debugger command to get AMOLED screen mode?

[Karlzbad]

On my note 10.1 or Tab S3 I remember some update took away screen modes and I downloaded something to get AMOLED screen mode back. I do have this Game Tuner_v3.4.05_apkpure.com.apk sitting in my downloads folder on my windows laptop, might that work?
