Sort of. It just changes what challenges you face, and what trade-offs you make. And to fill in the shadows properly, you need to shunt some light across from the LEDs on the opposite side.

Amazon seems focused more on light uniformity and removing the "book wedge" look to the light guide. Which is fine, but it is coming with trade-offs. The closest thing to what Amazon has achieved is the Glo HD, but even that basically is a statement that they are making different trade offs, and doesn't quite eliminate the "book wedge" look. Just very good at minimizing it. But it is still trade offs, do you value color uniformity or light uniformity?

Just to give folks an idea of how far we've come in the last decade on this sort of tech:
