Take a Good Quality Screenshot with AR

Hello,

I'm working on an AR application that lets you click a button to snap a screenshot that would include both the virtual content and the live feed camera background. However, while the virtual objects produce crisp images, I'm finding that the quality of the image coming from the camera feed is significantly worse. This results in an odd image where if you zoom in, all the virtual objects are sharp but the rest of the image is blurry.

Does anyone have any suggestions for how I could sharpen up the camera feed background when taking pictures? Currently, I've tried the ReadPixels and ScreenCapture.CaptureScreenshot method.
