Kodi 17 switched to HDR on start. (creator Update)

Hello. My Hardware is Nvidia 1060 and Samsung HDR TV. I start Windows 10 with yesterday installed Creators Update and latest Nvidia Driver and If i start Kodi 17, TV switch to HDR Mode always. Also on surface and non HDR Movies. Good for HDR Movies but bad for non. Windows 10 Media Player does it right. Is there a solution for this?
