If the player isn't very powerful, it will reproduce the video at core quality. As players have more and more power, they will be able to "read" more levels and achieve better quality. This is more efficient than having one stream per quality as each level uses the info contained in the lower levels.
MV-HEVC is the 3D equivalent for h265 of MVC for h264, which what is used to encode 3D blurays in full quality. So 3D Blurays use MVC, 3D 4K Blurays will use MV-HEVC.
SHVC could, for example, allow the main/core encoded layer to be 1080p/8-bit while the extension layer(s) could add the extra information to bring the resolution up to UHD or for increased bit depths, etc. The simpler codec used by for digital cinema does something similar where the main layer has 2K resolution and the extension adds the additional info bring it up to 4K. In this case the extension layer requires a much lower data rate to increase the resolution from 2K to 4K. This is done because most commercial cinemas still have 2K projectors while 4K is still rolling out. The same data source works with either 2K or 4K equipped cinemas.
