dslr – Are cameras without mirrors more sensitive to sensor dust?

According to an answer to the question Why is the shutter not closed by default on mirrorless cameras, while it is closed on film cameras? mirrorless cameras have a shutter "open by default".

In addition, the mirrorless cameras obviously have no mirror.

Thus, when changing the lens, a mirrorless camera has a fully exposed sensor. On the other hand, a digital SLR has a closed shutter and a mirror in front of the sensor.

Do these properties make mirrorless cameras more sensitive to sensor dust?
