From my results, only my Nvidia Shield and Zidoo X9S, and some of my **cheap Chinese** boxes running LibreELEC or CoreELEC could play that video.  Even my moderately powered Windows 10, desktop computer could not play that movie.  I do not have a 4k firestick to test.

To be noted, I have tested numerous 4k clips, and most of those clips play on most of my devices, but this REAL movie will NOT play on those devices.

 A lot of early 4K content was 4K h.264 8-bit and 4K h.264 8-bit content will play on Intels from around Haswell onwards, as these devices had h.264 hardware acceleration that was good enough to play this.

However - real world UHD Blu-ray movies (which can now be ripped) are in 10-bit HEVC/h.265 and usually also in HDR10 format.  This is much more demanding to play - so needs a more recent playback solution - and you also have to factor in the complication of HDR output or HDR->SDR conversion. You will also see that UHD Blu-ray lossless rips can often have very high bitrates - which will also stress network connectivity if you are streaming them from a NAS or similar.

What do you mean by **mobile** format?  A format for playing on mobile phones - or something with smaller file sizes and lower bit rate (and thus lower quality)?     
 I did not know what word to use instead of **mobile**.  I mean a ripped copy of a 4k movie that can be used with a storage device and not a Blue-Ray player.  I am really behind the media cure.  I am still slowly converting my DVD rips to BlueRay rips.  I just purchased the ** Back to the Future ** series on Blue-Ray and ripped them.  I am trying different methods to convert those rips to .h264 or HEVC, natively, they are encoded with VC-1.

If you have the storage capacity - why not leave them as is? (That said some platforms have issues with high bitrate VC-1 content)

After ripping all my CDs to 192k MP3 back in the day, and then re-ripping them lossless a few years later, I'm now very much of the view that if at all possible it's a good idea to rip DVDs, Blu-rays and UHD Blu-rays losslessly. If there are extras you don't mind not having (and are happy to go back to the discs for) then just ripping the movie can save you a useful amount of space.

There are a number of modern, relatively low cost, Kodi platforms that can playback lossless UHD Blu-ray rips now (such as a number of AMLogic platforms, the nVidia Shield TV etc.)
