It depends on the result if they invalidate your points for relatives.
In the scenario where you're deducted those points but you're still above cut-off, two options are possible. Either they'll request you for additional documents, or they'll just remove the points and move on.
In the scenario where you fall below cut-off for your round, you'll be informed accordingly and either requested to show more proof of relationship (ADR) or given a procedural fairness letter, stating that if you fail to provide proof of relationship, your application will have to be assessed as is.
But it all depends on the tolerance of agents/officers. Maybe what you've given them is enough, but I find it unlikely.
