The second picture reminds me of Apple OS X by a lot.
Yeah, the floating middle menu bar has been copied a lot. I'm not sure if the overall design started with OSX or KDE. KDE definitely had it a really long time ago. The super sized icons, though, is definitely all OSX.
Maybe your package repo is out of date, I tried this just now on my Mint desktop and it worked fine... but the direct links that you show do not exist.
Find it odd you have GNOME at the bottom. Again though, I haven't given them enough or really any time as of late, to have an opinion. GNOME at least was my favorite but they could have ruined it in recent years.
