I noticed this on Air Canada, Calgary-LHR last week. Hadn't flown with them recently, so didn't see a pattern. I too like to check from time to time, and I'm sure the cabin staff like it too - reduces the number of questions, for one thing. However, I didn't even manage to watch the movie due to the miserable size of the screen, (no seat-back screen either) and other distractions that I have posted elsewhere.
