Are there any lollipop lock screen settings?
There is a very clean, minimalist approach to this issue, but it involves the use of a third-party application named AcDisplay. I've used this app in the past and it replaces the traditional lock screen with a rather beautiful one (IMO), with notification access too.

See screenshots:
