Two anecdotes here:

In EK F, I like how they have 2 layers of shades, 1 that is actually a shade, and a 2nd that is a blackout shade so you can keep natural light in your suite without pissing off the whole cabin.

2nd, I was on an AA domestic F flight a few months ago and the pax that was in one of the window seats was a deadheading captain who had fallen asleep before they asked to put the shades down since it was an early AM flight ex-DFW. So the FA went and found a long wooden stick or broom or something so she could lower the shade without waking the captain
