The netinstall image *is* a CD image. For example, from https://cdimage.debian.org/cdimage/release/current/amd64/iso-cd/ : What is a netinst image? The netinst CD here is a small CD image that contains just the core Debian installer code and a small core set of text-mode programs (known as "standard" in Debian). To install a desktop or other common software, you'll also need either an Internet connection or some other Debian CD/DVD images.
The "other *CD* images" is incorrect since we do not produce other CD images any more. The /CD/http-ftp/ states: "it's possible to use CD images (700 MB each)" which is equally incorrect. This may have caused OP's misunderstanding.
