So this power supply states that it has over 95% efficiency.

The power brick, as far as I can tell, states that it has 90% efficiency.

Is it safe to assume that after looking 10% efficiency from the AC/DC power supply, and loosing 5% efficiency from the DC/DC power supply, the total efficiency is arround 85%?
