On my photo, the ICC version is 2.0, however the ICC datetime is 2009.
Does this mean the device can not predate 2009, and that the photo must have been taken after 2009?

No, it does not necessarily mean that. It is basically impossible to determine the provenance of a photo just from the photo's EXIF data. The ICC DateTime could have been manipulated by just about anything that handled the image file:
Also, ICC version 2 is much older than 2009, considering that according to the ICC itself, version 4 was published in 2001.
