Because Blu-ray never supplanted DVD. Yeah, there is a lot of VHS content that never even made it to DVD. But it would be more likely to make it to DVD than VHS.
Blu-ray is not niche, but it's not the earth-shattering success of VHS and DVD. Ultra HD Blu-ray is niche. It's more mainstream than Laserdisc and some other formats, but it will never reach Blu-ray levels, let alone VHS or DVD.
Digital distribution seems to be the mass market successor to DVD.
