I installed @fandangos bigger buffer version then downloaded @gil80 CosmosLaundromat files.

My Shield is typically setup for 4K59.40 Rec 2020 Dolby Vision and HDR Ready. Automatic Color Space switching on.
The TV is a Sony X930E - supports HDR and Dolby LLDV. I have an HDFury Diva which shows me what is being sent to the TV

Kodi mostly defaults except enable frame switch on Start/Stop.

When Kodi first starts, Diva shows:
4K59.93 422 BT709 12b 593Mhz 2.2           (I believe the 2.2 is Gamma)

Playing Cosmos DV it switches to LLDV mode and BT2020:
4K24 422 12b LLDV 297Mhz

When playing stops, the Shield returns to the 4K59.93 422 BT209 12b 593Mhz 2.2

Playing Cosmos HDR10 it goes back to BT2020:
4K24 422 12b HDR 297Mhz
Diva also shows the HDR10 metadata:
RX SMPTE ST 2084 Lum 4000/0.005 MaxCLL/FALL 10000/3551

When playing stops, Shield returns to default (BT709)

Playing Cosmos SDR, Shield stays in BT709:
4K24 BT709 12b 297Mhz

When I switched the shield to default  to Rec 709, it still does the 2020 switching on DV and HDR10.

I also tried the .mkv files. I typically go in the sequence P4, P5, P7 FEL, P7 MEL and P81.
First time - P4 played fine, P5 started ok, then after ~ 15 seconds, hung up then blanked the display for ~10 secs. At this point, I could not access any of the demo files over the network (NFS mounted NAS). Server timeout.

Restarted Kodi - network back
Went through the sequence again. All played fine on first pass. On seconds pass, P4, P5 P7 (both) played fine. I stopped before the videos were done.
When I played P81, it started fine but ~5 seconds later blanked and returned to the Video menu. At this point, the network was gone again (Couldn't connect to network server)
