This tree isn't in the RHS Plantfinder so I think we can assume it isn't available in the UK.
The same, or more or less the same, might be available with a different cultivar name. That's why I suggested asking at a large tree nursery, one where people know about tress, not a GC.
Probably not a job for a TV presenter either.
