Not to be cynical, but I'm pretty sure it was all just trailer-material concept imagery, a display of engine capability. The likelihood of each of these obscure images of having importance in the final product isn't high.
Some of that is as-is work in progress in-engine stuff. Some of it technical tests for capability, some of it actual work.
