Honestly I think the situation is even worse on a laptop. Unless you're pretty wealthy, you and probably most people you know have a TV screen that's small enough and far enough away from your couch that your laptop sitting in your lap actually beats it in pixels / degree. I've got a (old) 50 inch plasma set, and since I'm not sitting 4 feet away from it my laptop easily beats it.
On the other hand if you really can't tell the difference between a 2 GB encode and an average sized encode, say 16 GB, it's a good hint to make an appointment with your eye doctor. (I'm nearsighted, so I can't even tell 576p from 1080p on my TV without glasses.)
