I thought so too, but if you consider they removed the "from", "to", "subject" and top actions panels, the original had less content space. On the screenshot, the original had 152px of content height and the new one has 232px, ~ 150% of the old one. The one on the right shows a picture that's also content. I assume they redesigned the email thread so the box above the current email is the mail the person is responding to, with the pictures attached.
I think you’re measuring the wrong thing. Most email apps (and I sure hope the app in question is in this category) make the from, to, and subject lines part of the scrollable content region. In the example in question, I doubt they removed it — they scrolled it off the screen.
Amusingly, whoever made the blog post or perhaps the slide with the “4x faster” star seems to have doubled down on not caring about space allocated to content - the “4x faster” star also obscures the content!
