Is there reliable information to know where D1 / Gen 3 approved oils rank regarding wear protection ?

The pretty tight window of specs on d1 oils plus the presence of a paid license pretty much guarantees any slight differences you may see will not be statistically significant over the long term; I.e. they’re all the same.

The only place where this doesn’t apply is a specific blender who uses d1G3 add packs and then adds some additional “top-up” treatment for additional protection. But this is not a licensed d1G3 offering if you’re worried about warranty coverage.
 
You won't find rankings published, but many companies make specific claims for how well their oil performs in the Sequence IVA or IVB valvetrain wear tests used for the API and Dexos standards.

Castrol Edge claims 6x better wear protection than the minimum required in the IVA test, which I suppose means 83% less wear. Amsoil SS claims 77% less wear. Pennzoil Platinum claims that "No other leading motor oil performs better" in the IVA test, which would make it at least as good as the Castrol Edge (unless Pennzoil decided that it doesn't qualify as a leading motor oil).

I've seen some results from independent IVA tests in studies, and those oils also produced around 80% less than the allowable wear. It seems this test isn't very stringent, and most oils will perform similarly.
 
It can’t be used to evaluate between different oil specifications. The Lubrizol site has explicit wording about that…
It does seem like Lubrizol at least makes an effort to make the charts comparable to one another. It's just that it's not always possible to know whether one test is more stringent than another if it uses a completely different engine and test procedure. It's a judgement call, hence the disclaimer.

Usually if two standards use the same test with the same limits, they'll have the same ranking, like API SP and D1G3 do with the engine wear test. D1G3 gets bonus points for piston deposits and sludge since it uses the same tests as SP, but with a more stringent limits, and it also has an additional sludge test.

The ACEA standards use the same valvetrain wear test as SP and D1G3, but they get a higher ranking due to the inclusion of an additional engine test that measures the wear of more engine components.

I've noticed a few examples where they clearly get it wrong, but not by a whole lot.

How would the claim new and improved rank?
 
As has already been noted there are limitations of that tool. Plus they aren’t graphs of absolute numbers anyway. They are areas of emphasis for that particular approval or license.


Interestingly though…

There are definitive numbers there which do prove beyond any doubt that Porsche C30 , C20, A40 and MB 229.5 are much harder to hit versus regular API standards aka numbers. Like Noack being less than 10 percent for MB and Porsche vs 15 percent for API .
 
4 ball bearing wear test ?


Primarily a grease and EP gear oil test.

But really, what OP is asking for doesn’t & won’t exist. And really can’t exist. As the metallurgy and surface finish changes from not only engine to engine. But also manufacturer to manufacturer. And engine type to engine type.

There’s so many variables there it would be impossible to track. “Oh you have 2 micron more surface wear because the tooling on the cylinder hone wasn’t brand new.”

Great. B10 won’t statistically change.

Sure, but those numbers don’t have any relative values to compare with the Lubrizol tool. That’s part of the approval/certification requirements.
