A difficult question to answer as Audi have never made any information about level changes publicly available.
The MMI system consists of a 'control program' - the one that drives the buttons and the screen - that runs in the 'Control Head' [aka Interfacebox] which is ECU 07 in your car. It manages the devices on the optical MOST bus - the media ECUs - such as radio, navigation, CD, TV, Telephone.
An MMI update CD will update two separate aspects; it provides a new version of the control head program and will update any media ECUs with 'old' firmware [but not the Navbox in the boot - that's updated by Navigation DVDs]. The MMI system controlled by the buttons may provide new functions [and change the menu layout occasionally] and the media ECUs will have either faults fixed or new capabilities. None of this is documented; much of what is known is by experience only and often only subjective.
One real noticeable 'benefit' was the introduction in later versions of the ability to have 'birds eye' views of the Navigation map. This apparently needs MMI 3460 [not a typo] AND a Navigation DVD of 2007 or later. Have you got Navigation and if so, can you see 'birds eye' with your 3450 level? [3450 is not a common level on A8s].
Note that your level dates from 2006 and that the 5570 version dates from 2008 - so two years worth of changes.
If you list the ECU name and firmware levels of the Media ECUs in your car - get this from VCDS or by going through the MMI red 'software update' menu and noting the name and SW level 4 digit number - we'll be able to tell you what code is changed and possibly guess the consequences
