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.

The 33GB layers used as part of the BD-XL/UHD Blu spec were actually created back in the late Noughties for use with 3D initially, but nothing happened because 50GB was fine for most 3D features in conjunction with MVC difference encoding (longer 3+ hour features having to be split over two discs). As said, there were no commercially replicated triple layer discs at all until UHD disc (XL being a dye-based recordable solution).

It's funny how badly wrong Wiki gets this stuff, AFAIK they still state that 66GB discs have a lower max video bitrate than 100GB which is nonsense as they BOTH have the maximum 128 Mb/s available to them.
