Widespread, no.

I have yet to see an android phone manufacturer heavily investing in 3d face mapping. Apple does that since 2017. Google launched a phone with such features but realized that wasn't their business. The iPhone X didn't just come with just another biometric system. It was a mere investment into technologies that would make that headset a reality.

Another example is memoji. While it's fairly accurate and fluid due to the 3d sensors, other manufacturers tried to copy it by using various techniques to transform mere 2d data from a camera into animated faces.

That makes me think that while Apple spends money developing quality products and a slick ecosystem, others spend money to develop cheaper products.

There's nothing like Apple, and VR is still an expensive niche. For many people who are on that niche, spending that amount is just a little more than usual. For people who are (fully) into the Apple ecosystem, it's also a little more than usual. And I think it's going to take more than a decade until the major VR manufacturers catch up with Apple vision while offering a lower price.
