I'd say this falls very much under the category of "personal preference".

Sounds like you are assuming if you pause the movie, that no one cares
what is on the screen -- i.e., bathroom trip, answer the phone, etc.
While often the case, there's a whole different reason: Because you wish
to see and examine what is on the screen at that moment.  You really
don't want a display in the middle of a discussion of the fine points of
composition of the scene to suddenly go blank because the computer
decided you are having a long stop at the bathroom, right?

That's somewhat of a long-standing tradition: I have a 60+ year old
movie projector which does much the same thing -- when you "pause" the
movie, a heat filter is put in between the projector bulb and the film
to keep the bulb from melting the film, and if I recall properly, the
fan kicks up in speed a bit to keep the air moving past the film and the
filter from over heating.  You COULD just power down the projector,
too...but that's the "off" switch, not the "pause" lever.

Personally, I'm slowly losing interest in screen blanking.  LCD screens
draw little power when on, they don't burn like CRTs did.  I do often
let the blanker turn the screens off for me, but that's mostly because I
know it will, if I'm not lazy, I'll hit the power switches on the monitors.

A laptop plugged into the wall...why power down the screen at all?  A
laptop running on batteries...if you aren't going to use it, why not
just suspend it?  No, I don't fully embrace what I'm advocating there,
but I'm having trouble explaining to myself why I don't.  I find myself
annoyed by blanking far more often than I say, "I'm so glad my screen
just blanked", and I'm inclined to think that means I'm doing it wrong.

Nick.
