BLUE TONGUE SKINKS

Hello, I have been puzzling over the identification of my pet for a long time, my friends advised me to write to this forum. I apologize in advance for any mistakes, English is not my native language and I have to use an interpreter.
He was bought a year ago in a pet store, a baby the size of a palm. Now it is already a powerful large beast 52cm long, 624g. Male 100%, showing hemipenis.
But now I see that it is significantly different from the usual Tiliqua gigas gigas. Please help identify its subspecies.

Halmahera

Thank you! We also suspected that it was Halmahera, but decided to ask again. The skink stopped sneezing when I raised the humidity from 60% to 80%. He definitely doesn't like dry air.

Nice looking Halmahera
