Classic Chromecasting is a totally different technology. Especially towards "whom" decodes ...

What does VLC do on your device?
In kodi you can disable Mediacodec Surface (just the Surface part) then we scale it - but most likely the device is too slow for EGL import, scale and rendering again.

Edit: Did you post the adb logcat somewhere already? Perhaps the stick itself tells something what it does not like.

As a new weekend I had some time for it again with these reports:

- Kodi with 'Media Surface' 'off' seems play the file. Not sure that absolutely fine but seems play. Purple D+ logo still purple instead of blue but at least we got continuous playback.
- With Chromecast casting D+ logo also purple but plays fine.
- With default VLC settings the problem is the same as with Kodi.
  Default settings: HW acc.: automatic; Color format: RGB 16bit; OpenGL ES: Automatic; (there were something forth relevant settings but I simply forgot and already uninstalled VLC)
  Changes on any those attributes (forced HW acc.; YUV color; etc...) not help except the OpenGL ES. With forced 'on' of OpenGL ES the video works (while it does not warn but need to restart VLC). (Not sure that on the same way as Kodi does with 'Media Surface' 'off'.) D+ logo still purple but the video playback seems continuous.

My theory still is because some header difference in the file the result is SW rendered instead of HW. The mentioned OpenGL ES difference is not yet understandable by me.

Seems all 10bit D+ files have the same problematic results. Mediainfo of the video streams is the following:
