App layout Sizing

I recently switched up to a new PC with greater GPU power & use a 65" TV so my native Resolution is 3840x2160. I have adjusted the windows sizing option to try and find a workable common ground. This current set up is in a family room/office space, so the screen is on a wall, 12 away, not on a desk 3ft away.
For the most part, im managing to find usable sizing with the few apps I'm using, so far. Is there a way to allow for upscaling of the app to accommodate this issue in future releases? Right now, the icons are nearly unviewable & the type is tiny. The ability to upsize the layout and icons by 300% or even just 150% might work. Just a thought...Thanks
