It turns out that the piece of plasterboard above the window (the bit in the
recess) is the wrong way around.
Does it really matter or should I swap it in the morning?

It doesn't make a blind bit of difference, I've put full boards on back to
front and it's no different.
The dark side is slightly less flat, than the finish side, and may have
a slight visible paper seam on the edges. Makes naff all difference if
its being skimmed, and not much if being finished directly.

Thanks to both of you.
I'll leave it as it is.

it doesnt matter. There's greater risk of minor blemishes on the other
side, but plastering or filling take care of those.

I once asked a plasterer about this, and he said that one side is more
absorbent than the other - and gives less time to work the plaster - but
the difference is small, and doesn't really matter. ISTR that he also
said that you use one side for skimming and the other side for Artex.

Ask the manufacturers. They say, use the white side for plastering and
decorating of all kinds.
Differences are:
The actual paper - absorbency, smoothness, etc.
Voids under the paper (I think they make it white side down so any air
bubbles will be under the grey side).
How the paper wraps - it is double-thickness near the edges on the grey
side.
But as half the plasterers who are asked seem to get it wrong, I'd imagine
a lot of plasterboard has been fitted and plastered the wrong way round.
And in non-critical situations it probably makes very little real
difference.

Last time I used it the principle difference was that the edge was tapered,
on one side only. This was to accommodate the nasty european habit of taping
the join, filling the taper but not skimming the whole face, just painting
or papering onto the plasterboard. In British practice it meant that if you
nailed the edge of the board with it the wrong way round you got a nail head
through the skim, or a piece of broken plasterboard.

Typical US practice, too.

I suggest you don't buy tapered board if you're going to skim it.

I was taught this as the preferred approach on a DIY plastering course
in Britain recently too.
I chose to use tapered when lining this place with isulation backed boards-
meant I could get a proper taped joint with thick scrim/tape and plenty
joint cement - and no problems with "undulations" or tape "poking through"
when skimming after.
YMMV

Its partly historical - the makers used to specify one side for skimming
and the other for decorating. These days they specify light side for
both. Many builders etc do not respond well to learning new tricks!
Not uncommon in England either to be fair. A favourite technique for
many shop fitters.
There's nothing wrong with it.

Reminds me, before I could do my own plastering, I had boarded a ceiling
and then got a plasterer in to skim it. Part way through, he said to me,
"Next time, can you put the board on the other way up?".
I asked him if he really wanted to plaster straight onto the foil, at
which point he looked a bit sheepish, and carried on skimming.
