Maybe a silly question but are you definitely looking at a Raw and not a Jpeg file? "Embedded" is what normally shows up if you are viewing a jpeg. I have version 5.6 and the Olympus colour profiles are certainly still there.
On my Windows system all the profiles supplied by Adobe are stored in
C:\Program Files\Adobe\Adobe Photoshop Lightroom 5.6\Resources\CameraProfiles\
so maybe check that folder.
