DTS-HD not working, getting DTS instead

Hello,

Not sure if this is a problem with Kodi or just me not reading MediaInfo right, would appreciate someone’s help please

Setup details:
Kodi – 17.0
PC – Lenovo T510 (nVidia NVS3100m)
OS – Windows 10 64-bit
AVR – Onkyo TX-NR717
Connectivity – Laptop (DisplayPort to HDMI converter) -> AVR -> TV

The NVS 3100m doesn’t have hardware support for HD formats however it does support 8 channel output. Therefore I have set Kodi’s audio settings to WASAPI and enabled passthrough only for the lossy audio formats (DTS-HD and Dolby TrueHD disabled).

Problem:
I can get TrueHD audio decoded in Kodi and come to my AVR as LPCM (I can hear the beautiful quality immediately) but DTS-HD movies are not decoded and instead are bitstreamed as DTS (AVR says “DTS”).

This is what MediaInfo is saying about one particular movie I have however I can’t tell if it’s HD or not as even MediaInfo seem unsure??
