Question 3D triple layer Blu-ray 3D discs that (2D only) players cannot read.

I always thought that the largest capacity Blu-ray 3D disc has the MVC encode authored on a two-layer 50GB disc! Apparently there are larger capacity triple layer 3D discs?

Per Wikipedia:

On December 17, 2009, the BDA officially announced 3D specs for Blu-ray Disc, allowing backward compatibility with current 2D Blu-ray players, though the compatibility is limited by the fact that the longer 3D discs are triple layer which normal (2D only) players cannot read.
Has anyone measured the GB capacity on an existing title authored on a 3D triple layer disc?

Has any 3D Blu-ray Disc ever taken advantage of the additional layer?

I've certainly never heard of one. You can buy 100GB blank BD discs though, but those are 4-layer.

I don't know of any triple layer 3D discs. Blu-ray and Blu-ray 3D use standard BDs with 25 GB layer sizes; max of 2 layers (50 GB).

The 4K UHD spec uses BD-XL discs with 33 GB layer sizes; max of 3 layers (100 GB).

That paragraph on Wikipedia cites the following press release from the Blu-ray Disc Association, which mentions nothing about triple layer discs as part of the 3D spec. In fact, I don't think triple layer Blu-ray discs actually existed when the 3D spec was finalized back in late 2009.
