People were prototyping ambilight type stuff back in the DK1 days. Trouble is, it doesn't improve immersion because objects disappearing out of view is still jarring. At least with a black edge you can imagine you're wearing a dive mask. If you want to know what developments are or aren't going to find their way into future VR, track down Michael Abrash's talks from Oculus Connect and other conferences. Realistically much of it is over a 5-10 year timescale, but a lot of research has been done in the last 5 years. Many things that seemed like good ideas in 2012 turned out to be dead ends, and some surprisingly simple things have been discovered (like a "virtual nose" reduces VR-sickness, which nobody anticipated).
