That isn't a patch, that is playing a video at startup to workaround the dark screen, and is something I think many of us would be opposed to. It's easy enough for someone to set a startup video if it bothers them that much.
Personally I'd be much more bothered by the extra time taken to start the box because of an intro video playing after boot - the slightly darker menus don't affect usability at all.
First, it really is a workaround and not a patch.
Second, it really should be up to the user and not default.
Third, even if it has double use for us amlogic users, any further effort should benefit all Kodi users imo. So, if anything, somebody with more skinning experience than me ( I would need more time than I have atm) could implement and make a pull request for 'add startup video' to estuary. There is a GitHub. Would make sense anyway, since there is this startup animation thread on Kodi forums.
