Overfilling washing machine with load detection?

I have a modern washing machine from Bosch with load detection for

9 kg of laundry purchased:

When you put the laundry into the drum, the weight of the laundry is displayed.

I put in 7 kg of laundry (mixed) and had to press a bit to get more laundry in.

Can you then “push in” more laundry, even if the machine is already full, but the load detection still shows about 2 kg remaining volume?

Or does the rule still apply that there should be about a hand's width of space in the drum?
