You're a full PIC, however will take a while before being appointed as leader Captain on international flights

Hhmmmm hold on a second. Lets give the OP a little more clarity on this one.
When you finish training, your name will indeed appear as Cap on the flight log compared to FO when you are in training so you could say this means you are a PIC.
However you are signed off as a B Captain. By the OM this means you can take off and land with a C FO or higher however 777 fleet view that differently. As a B Capt on 777 you can ONLY take off and land with an instructor in the RHS and not with an FO. Sooo do you think you are really PIC when you are not even able to land with an FO?!?
Bear in mind that B Cap status can stay for a long time too. Some guys only progress to C after more than 1 year as a B even if they have flown the 777 for 5-10 years before 😩😩
When signed as C Captain then you might be designated as PIC on domestic flights. Perhaps later on as PIC on international but at present there are about 15 international leader Captains on 777 out of almost 100 foreign pilots just to give you an idea.
Just wanted to give you a bit more insight.
Hope if helps.
Cheers,
