ScreenEnhanceEngine working ?

[E-OSy]

Good day , I'm using the Miui.eu 12.11.18 rom and would like to know if these features can be activated or if they are placeholders as I can't really see a difference

com.android.settings.display.ScreenEnhanceEngineAiActivity ( Ai Image Upscaler )
com.android.settings.display.ScreenEnhanceEngineMemcActivity ( Video FPS interpolation )
com.android.settings.display.ScreenEnhanceEngineS2hActivity ( video HDR )
com.android.settings.display.ScreenEnhanceEngineSrActivity ( App Upscaler if supported by app )


Except SuperResolution everything can be activated

What I initially wanted to try was the new Reading Mode aka Paper mode , but this doesn't work in my case.
