@Luke will confirm, but I'm sure with the way the Tizen app loads the media when DirectPlaying, it really should make no difference as to whether the server is detecting 3D or not as the client does nothing special for 3D files. I believe the auto-switching of 3D on the TV is completely an automatic function of the player. Therefore I don't think that the naming of the file should impact this. All the '3D magic' is in the mkv file and stream metadata.
As a test, rename Ronin to remove all the 3D tags and rescan the library to be sure that the server no longer detects the file as 3D. I suspect that it should still autoswitch on the TV with the Emby app.
