It is just Ethernet traffic, so there should be no difference in emission.
Immunity might be a problem, since during some tests (e.g. EFT), temporary loss of packets and link-drop will most likely happen. That is not an issue with regular data-only Ethernet applications, since Ethernet normally checks for errors and re-transmits if packets have been lost, but real-time applications might suffer. It could disturb video if there is not enough safety-margin in the code that allows for the lost packets to re-transmit without disturbances (as defined by the manufacturer AND EN55024 section on LAN). I do not know enough about the application, but check for that. That can happen e.g. with IP phones, where link-drop results in a call-drop, which is then a test failure (it requires user-intervention to redial, so the Ethernet self-correction does not work).
