No, I've never seen Google Photos reflected in any Google Drive interface (web, OS integration, etc.) which on the one hand makes sense (think of Google Photos more like a database-driven black box app than a hierarchical filesystem) but on the other hand Google Drive does show gdocs, gsheets, etc. (which is also sort of a black box app, as the "files" seen in GDrive are merely lightweight stubs).

Only in storage quota views do Photos and Drive (and Gmail, etc.) commingle.
