That’s correct. My dad owned a darkroom business/photoshop for years and we had a nice home darkroom. Kodachrome could only be developed by Kodak and I think one independent business that bought the necessary equipment from Kodak as they were winding down Kodachrome:

Kodak simplified the Kodachrome development process over the years, but it was never viable to do at home.

Honestly, anything but B&W and E6 was a PITA to do at home. Even the color negative process (C-41) was annoying at home due to the extra chemicals and temperatures required.
