Are you suggesting Uber maliciously edited the dashcam video to hide the jaywalker? Or that a better, human-readable (ie not raw sensor data) version of the video exists and Uber has not released it?
There are no alternate versions of the dashcam available. However, there are comparisons of the same location made by other drivers that make it pretty clear this is a fairly well-lit stretch of road. [1] It looks nothing like the released Uber footage.
