It appears the new Flat theme is not included in the default CSS library files (even if it is available in the source Kendo UI distribution used with the Bootstrapper). I assume this is a Bootstrapper configuration setting that just needs to be updated.
For reference, the themes I see are: Black, BlueOpal, Bootstrap, Default, HighContrast, MetroBlack, Metro, Moonlight, Silver, and Uniform.
It will include the Flat theme now, assuming it's found in the user-supplied Kendo UI sources (i.e. it won't show up if the user provides an older version).
