That seems like a fair characterization. From what I remember, the powerEfficient bit alone has not been considered to have privacy implications. The browser may in certain cases choose to set powerEfficient=true even though there's no HW support (e.g., low resolutions may for example be considered to be powerEfficient without HW support).
