My browser (and curl) both disagree with you:
curl -v --compressed 'https://lwn.net/' > /dev/null 2>&1 | grep gzip
> Accept-Encoding: deflate, gzip
< Content-Encoding: gzip

This command is obviously without any output.

$ curl -v --compressed 'https://lwn.net/' > /dev/null 2>&1 | wc
0 0 0

Perhaps you meant: curl -v --compressed 'https://lwn.net/' 2>&1 > /dev/null | grep gzip

You are right, I'm using ZSH and didn't realize that line was not portable across other shells.

curl -v --compressed 'https://lwn.net/' -o /dev/null 2>&1 | grep gzip

also works
