Is it possible to grab screenshots directly from IR?

I'm trying to get extremely high-resolution screens of the title screens of Xenoblade and The Last Story, I'm using them as wallpapers for my iPad. I managed to get 4k screens with some downscaling, but it's still kinda blurry. I don't think I'll be able to push my monitor to do 6k or 8k, besides, my HDMI cable can't even support it. Is it possible to grab screenshots before they're displayed onto the window? Some 12xIR screens would be nice, and I don't think I'll be able to display 8k downscaled.
