Apple Watch is a good example of a recent "blue ocean" innovation. FaceID is a recent usability innovation of the kind Apple has historically been known for. I think they're still doing good work.
A marketing innovation certainly, but calling this a usability innovation is quite a stretch.

Many devices dont have the depth scan making it all pretty unsecure when you can unlock with someones photo.
So Apples inmplementation is probably top.
For example the Motorola Atrix was the first smart phone with a finger print scanner, but if you actually owned one of these you'll know that it was awful. It wasn't until Apple put Touch ID on the iPhone that people actually were interested in using finger print scanners, and the rest of the industry followed suit and copied Apple, not Motorola even though Motorola was first.
Another example is app stores. Apple didn't invent app stores. But after the iPhone added an app store, it changed the entire industry because of how easy Apple made it for anyone to develop for iPhone.
I would argue that the app store became popular because the iphone was already popular due to being the newest product from apple that had built a following with the ipods and keynotes where the journalists where applauding everything Steve Jobs said. It's easy to forget how bad the iphone was when it was first released.
