The techniques themselves are very cool and inspiring. That said, the reason such things do/don't take off isn't about how cool they are, generally. It's about how useful they are. Even for games, immersion and realism are secondary to gameplay. For most applications, it's hard to see how a "realistic window" is useful. A flat paper, paper-like screen is better to read off, for example. Cool tech. Definitely worth exploring gaming potential. Not easy to apply to other uses. There's no benefit to making an online shop window more like a real shop window. Catalogue is what you want in any case.
