That's possible. Is there an easy way to tell?
Looked through the output of ffmpeg and found;
Stream #0:0: Video: hevc (Main 10), yuv420p10le(tv,
bt2020nc/bt2020/smpte2084), 3840x1600 [SAR 1:1 DAR 12:5], 23.98 fps,
23.98 tbr, 1k tbn, 23.98 tbc (default)
So it is a 10bit file.
Another tip: I found upgrading the NUC's firmware helped a lot. However,
be warned that Intel has been removing support for Legacy booting in
newer firmware. So you might want to get yours to boot in UEFI first,
then try new firmware.
I suspect it's a hardware limitation, but you never know.
