You haven't been able to take screenshots of DRM controlled content for as long as DRM controlled content has existed. That's what makes it DRM. This technology isn't doing anything special at all. If you wanted to develop it for Windows, you could, and it would work the same way.

This doesn't sound very likely. In order to show pixels on a screen, something has to write those numbers somewhere. Screenshot should be writing those pixels to a file as an image format, not consulting whatever programs are running to ask if there are areas that they don't want to draw.
The pixels are literally encrypted on PCIe on their way over to the GPU, it's quite draconian. Been this way since Vista ("Blu-ray is a bag of hurt" - Steve Jobs)

That is a crazy thing to do! Looks like it's windows specific at least.
