Hmmm, not sure for a « real difference ».
You should do tests and see what happens.

(I've just done some, as I was curious to see the result. Took one of my
images, not exactly night but sunset with difficult light conditions,
1/25 sec, F/5.3, ISO 3200.
I've resized to 1024, as you mentionned earlier, and ran 3 compressions
with convert, quality 71%, 72%, 73%.
I got three identical images, more or less. I'm unable to say which one
is which one. But it could also depend on the image content.)

Anyway, if you really have the problem to fit under an imposed size limit,
there's no other way that tests and tries, and count the bytes. :)
