Ranked LP Gain

Above I attached my most recent ranked game at the time of posting this. I'm not usually one to complain on a forum, but I feel like this should be shared to where I might at least be able to get an explanation. I understand that I was on like a 3 game loss streak before this I think, but the ranks of everyone I was playing with as well as against was from Gold 1 to Plat 3, me being the only Plat 2. I received 9 LP for this win... This isn't even an instance like everyone else on my team got a normal amount and I got 9 because my MMR was down. My teammates also commented saying they only got 9 or 10 LP as well. Just thought I would share since I was pretty disappointed after carrying the game to get only 9 LP in which if I lose this next one, I would probably lose upwards of 19.
