the detection loophole has not been closed.

Not completely, but if I'm reading the paper correctly, they claim a detection rate of 91%, which is pretty high. Previous experiments had much lower detection rates. So while it may not completely close the loophole, it does make the detection loophole argument ("the photons you detected weren't a representative sample") much more "paranoid", to use your word.
