At the moment, the best you can do is:
Use Taifun's Tools extension and the "HideContent" block, which "moves" the screen up and behind the status bar.
Next make the status bar colour transparent, using the StatusBarColor property with 16777215.
What is required is to also make the status bar text either transparent or to go away, which is currently not possible.
Btw @User_Enforce is this app for your own personal use, if so then there should be a setting in your phone for this..
Too over come fear of height.
I understand but why the other games or apps are able to transparent and hide the status bar text, it should work on other extension
On which extension?
On potrait mode? If yes then which game and app provide some?
This extension or this extension
Yes and also landscape
It should be like youtube, whatsapp, facebook
But i dont know which game has fullscreen mode?
Like that?
Yep, with white screen background it looks great, no statusbar text visible
Acually i treid it and it acually did set the status bar to trnasparent
Thanks for letting me know
Edit : but what happen if you didnt set the status bar color?
Does it still adding black area with this block?
Don't know whether this is still valid:
If I knew how to set mDecorView I could have a go at an extension for this.
That didnt work either, maybe i will try something else
Did you get the same screenshots? If so, these are the only options you have.
Post screenshots from your device.
Then we will certainly reach more than 100 posts... without coming to a (satisfactory) solution. 
Why? It would be interesting. I would like to see at least the height of the status bar of your device.
My screenshots are from a Pixel 7 Pro, which has a notch. My first screenshots are from a Pixel 4XL, that doesn't have a notch.
