You can visit the theme gallery to take a look. The theme gallery does make a remote HTTP request, but a warning is displayed before this is performed. Once a theme is downloaded, occasional (but infrequent) HTTP requests are made to make sure it is up to date.
Note that when using a theme from the theme gallery, the internal theme is disabled. There is a button to disable any loaded theme gallery theme though.
The default theme has support for the prefers-color-scheme CSS media query, enabling it to be dark or light depending on your operating system preference.
