This JPG was 1943x1934 and 528kB, so 7.11pixels/B
My PNG was 1394x1132 and 272kB, so 5.80pixels/B
So the PNG was less dense at storing pixels, compression artefacts notwithstanding. I bet it would be significantly smaller if I disabled antialiasing on font rendering, those slightly blurry edges are what the FFT algorithm of a JPG likes to compress, and what a more straightforward spacial-domain compression like PNG is bad at compressing. GIF even more so.

Re-exporting that PNG as a PNG using GIMP outputs a file that's 224kB, so somewhat smaller, using maximum compression. I guess my screenshots aren't as compressed as they could be then.
But when I save that PNG as a GIF in GIMP, it's only 110kB. And when I then save that GIF as a PNG again, it's only 65kB. So I think I'm losing maybe a little bit of information by doing that, but it's basically not noticeable. Here's the GIF.
