While LibRaw states, "LibRaw is a library for reading RAW files from digital photo cameras (CRW/CR2, NEF, RAF, DNG, MOS, KDC, DCR, etc.; virtually all RAW formats are supported). It pays special attention to correct retrieval of data required for subsequent RAW conversion." Microsoft does not imply it uses that open source library fully. It explicity said "view Thumbnail and metdata" and no more. Based upon that explicit statement, I think it is presumptious to assume they use the open source for more.

And they use it to view photos in the photo app. They read metadata, and they add native viewing support. They say they do all of that too. Here it is again. Emphasis mine.
The Raw Image Extension adds native viewing support for images captured in raw file formats produced by many mid- to high-end digital cameras. By installing the package, you will be able to view thumbnails and metadata of supported raw file formats right in Windows File Explorer or view images in the Photos app. The current version of the extension supports a long list of cameras, however some Raw formats like. GPR are not currently supported.
