If this is going to be confirmed with more tests, i can see just 2 position for us to take.

1) p3netration/resistance is bugged and doesn't work. It will be fixed by a later patch (like mystery delay) and we just need to wait to receive it from CN. This could be the reason why tencent waited 2 years to test this officially.

2) It's a whale stat. In CN is not inusual to see people with 7+ k p3netration/resistance without spending directly in it. Maybe it's like control and you need some big numbers (which we don't have yet) to effectively feel the difference.
