FTW: High 10 Profile (Hi10P, 110) Going beyond typical mainstream consumer product capabilities, this profile builds on top of the High Profile, adding support for up to 10 bits per sample of decoded picture precision. 10 bit is a sample bit depth precision ranging from 8 to 14 bits per sample of the frame. what are you looking for, I've already posted references to 10 bit with a fire-stick, further posted links to 'state of play' for most of these streamers.

Unless you're looking for broadcast quality equipment?

I have a lot of content in this type of file, most of them are Anime and animated comics. I'm looking for something that's capable of play them without transcoding. I don't know if this Fire Stick could be or not. 

The only Hi10 h.264 hardware decode chipsets that I'm aware of are some of the RockChip range - which has some support in LibreElec.  However some of the more powerful ARM SoCs without hardware decode are able to software decode Hi10 1080p stuff these days.  

The most powerful ARM SoCs at the moment are things like the N2/N2+ (based on the AMLogic S922X) range from ODroid and the Apple TV 4K (that doesn't run Kodi, but does run a fork of it called MrMC which has Python Add-on support removed to comply with Apple App Store policies).  I'd get people to test those too.
