Don't forget displaying owner information is also theme dependent - some themes don't show that information when locked. I had to change themes when I was using one that didn't display the information.

Yes, themes sounds like a plausible issue.
I think the OS does support screen lock with ownership display in most current versions (4.6,4.7,5.0).
