Possible efflorescence?

For the sake of 3 grand, I could certainly learn to ignore it!

I'd be more annoyed by the one at the front which isn't inline with the others.

Yes i replaced it with a new slab and it stood out. Jet washing will stand out too. Someone said a new slab would take years or weather. When the slab is wet looks exact match as I took one from the back. Managed to get all white marks off. Seems to weather in better each day so perhaps best to wait before spending alot on a driveway. Perhaps the slab will darken a bit more now it’s at the front? Also think maybe  lack of moss in between is also why it doesn’t seem exact. 

It does appear to have cleaned up all white ect well though
