When in Division 1 of a League, you usually gain less LP. This is because the system has to make sure you belong in the next League, since you can't drop back down to your previous League, without being inactive.
By lowering your LP gains, the system forces you to raise your MMR before you get into promotion.
Getting 12 LP for a win doesn't seem like a lot to me. My best guess is that it's a fairly average amount..
So, since you're now in Division 1 and you're "only" average, the system isn't sure if you can actually compete at Gold level. So in order to figure it out, the system is lowering your LP gains, so that you can increase your MMR to near-Gold 5 level, before you get to promotion.
