.... from the picture it doesn't even look as though it would
float an unconscious person face-up.

From the picture, they don't appear to be inflated.

Maybe they're just pictures!
Which of course are perfectly suitable for rescuing people involved in
pictures of a ditching
In Canada, where I live, we are not allowed to use boating life
preservers in aircraft that are beyond gliding distance of land -
we have to use certified life preservers for aircraft - and they are
REALLY expensive - and they have to be self inflating, and have to be
sealed in an air positive bag - so if it is breached we know before we
need it - and we have to keep them current!

Ah, we don't have to have them at all. Just one of those "nice things
to have" here in the UK. :-) I'm probably going to buy a couple of them
and maybe a life raft before I start doing serious over water flights.

I guess it's like anything else...put "CAA certified" on it and you can
at best double the price, at worst stick a zero on the end.

The last thing you want in a light aircraft is a self-inflating life vest,
especially if it's in a high wing plane.

Yes of course the actual life jacket is one of those inflatable things
which resides inside the collar that you see in the photo.

Here's a similar one sold for aviation purposes:
