The LEDs with addressable dies are solely the RGGB, RGBW, and RGBA. The solid colors are all discontinued, other than some old stock on the reds. You can tell by the LZ4-2. The two denotes the individually addressable dice on the 10W solid colors. If you see LZ4-4, it is a series wired LED, we don't want that :D.
We are working on a solution for the community for the solid colors since Mouser and Newark are not going to be carrying the solid color individually addressable versions on MCPCBs. They will be carrying emitter only, but unless you have someone to reflow them onto a star, that option stinks :'(.
