NdrStubCall3 was added in Windows 10.0.10240 and removed in 10.0.16299. It takes exactly the same parameters as NdrStubCall2 and there is no documentation on what, if anything, it did differently.
I found backtraces from [Firefox](https://bugzilla.mozilla.org/show_bug.cgi?id=1581719#c0) and [LibreOffice](https://bugs.documentfoundation.org/show_bug.cgi?id=140762#c7) that show that NdrStubCall3 calls NdrStubCall2.
