Hi Broe,
Where did you buy the COOD-E TV in the Netherlands? Because it should not be positioned as a mediaplayer, but a an TV Streaming Box.
Because KODI does support streaming, like a Mediaplayer, you can use it in this way.
But, DOLBY / DTS needs to be on passtrough, so trough a AMP or your TV must support DTS/DOLBY, then it will work / play.
