The update brings the OS version up to 8.0 and the firmware is version 2.19.400.1. Some users are reporting 2.19.709.2 instead. There’s a difference in the size of the update too – the former is 1.32GB, the latter is 1.58GB. It seems that the Android security patch level is January.
The changelog is pretty vague – beyond the OS upgrade, there are “system enhancements”. That’s still good in our book, so go on and check if the Oreo update has reached your U Ultra.
