The video in questions is just 17 seconds long video and starts off with dots in yellow, blue, red and green, which are used in Google logo. Even this video looks very similar to the Nexus boot video. As LG G Watch is a smartwatch, it is possibility that this might be a boot video for all smartwatches being produced under the Android wear range.
The other interesting details that have emerged from this dump are a set of watch-faces, status cards and background.
Google has already given a preview of LG smartwatch and the same is expected to be revealed at the Google I/O that is happening a little later in the month.
