As you already know DStv had Toonami running as a month long pop-up channel on the DStv platform to almost all DStv customers until the end of April even after its removal the channel still had an ongoing schedule for the rest of May.
For some reason the channel has been added to the Startimes (or StarSat) platform without any explanation or clarification from the platform on the duration of the channel or whether they plan to keep it full-time which seems unlikely.
Toonami which is owned by WarnerMedia targets the same audience as Cartoon Network the only difference is the channel is catered for superheroes. The channel carries action, drama and adventure.
The channel airs repeats of old DC Animation that once aired on Cartoon Network such as Batman, Green Lantern, Superman and Young Justice along with DC Movies.
This channel is just ripping off Superhero HQ for those of you who had DStv Compact back in March of last year at the time the channel was already ripping off the full-time Toonami channel on Kwesé TV till the brand shut down it's pay-tv service along with the full-time channel that had anime and selected Cartoon Network series at the time before being reduced to nothing but a pop-up channel.
It wouldn't surprise me if the channel eventually resurfaces again on DStv even after the channel's removal people still want the channel if it was on Compact you'd some happy faces over the channel's removal but since they made it more accessible more people grew attached to it cancelling out those that recieved the channel already under another name.
