Nope its a pure KC activities reg dog for a good few generations. If it was an ISDS registered dog it would have been registered by the KC as a BC. There are NO BCs on the activities register since BCs were recognized in the 1970s.
What is very strange is the owner is the breeder of the dog & it's mother & is the only one at the moment on the full breed register from the litter. They haven't converted the mother to a BC & the sire is a very well known stud & top winning Obedience WSD. Why they have done this I have my suspicions but I have no proof.
FYI an ISDS registration certificate reads Working Sheepdog(or Border Collie) not Border Collie alone. An ISDS registered dog would not need it's registration converting to Border Collie at the KC nor does it cost £100, no one has to say it looks like a BC & they do not require all the ABS health tests done. They just require a certified ISDS 5 generation pedigree, the ISDS registration certificate(or it's parents ISDS certificates & their pedigrees) & the special BC KC registration form, which explains which dogs qualify for automatic KC registration on the full breed register. Did you know non ISDS registered offspring of ISDS registered dogs can be KC registered on the full KC breed register, as can the offspring of a KC registered bitch & an ISDS dog.

The Kennel Club would accepted the registration of a Border Collie on the Breed Register when -
The dog is registered with the ISDS (International Sheep Dog Society)
Or, both parents are registered with the ISDS
Or, the dam is registered with the ISDS and the sire is registered on the Breed Register"
The KC hold a copy of the ISDS database
KC activities WSD are not the product of unregistered offspring of ISDS dogs for whatever reason(the usual one is the owners of the parents are not ISDS members)they are mainly dogs that allegedly look like a BCs but have unknown pedigrees & often other breeds/mongrels in their pedigree. You could register any dog as a WSD or any breed other than a BC on the activities register & they will be accepted as such. I have a dog of unknown breeding from Ireland who is a brilliant worker & clearly is a WSD as he can control Herdwicks one of the hardest breed of sheep to work as they are very difficult & have beaten many an ISDS trialling dog. He isn't very pretty & I doubt as conformation judge would consider him to be a BC par se, but I have turned down offers to buy him based on the quality of his working ability & no I do not use my dogs at stud especially my rescues.
