There's also the line length to consider. I've seen the same on my own converted Java code. Less lines of code. But you also get lots of a really short lines.

And some formatting actually spreads things out over multiple lines for readability. E.g. I use intellij's build in "put arguments on separate lines" a lot. Especially with named arguments, this is just nicer to look at. It's the same or less code but more lines. But less dense code. A more interesting metric might be simply the byte size of the source files. I would expect that to be slightly better than 11percent. Maybe closer to 20-25%.
