Thats the thing - regardless of how unique the name is, if someone could 'grab' the name it'd open the door for anyone to jump on board. And there's be a John Smith who'd ultimately take the piss. It'd be confusing if you didn't know Christopher Lloyd from Christopher Lloyd - but it their names. Someone can't claim copyright on them. It's just a can of unfair worms ready to be opened.
On the name though, if it is connected to Latif's birth name, Javid would likely have as much significance as to why it was chosen. Javid Prime probably got a giggle out of the confusion and moved on with Spyler Javid lies in wait to be updated.
IIRC per SAG rules two actors cannot have the same credit name.
One would need to change how they're credited.
