@blackbanana: Your TV has a dedicated chip which is designed for media use and has HW-decoding support for latest codecs. So yes, your TV is "better" = much more efficient in decoding your 10-bit HEVC-files. Kodi in general has never been quite efficient on SW-decoding in Windows platform. Partly related to its 32-bit nature and seems that there is also some inherent extra resource load present, might be related to whole complexity of Kodi, which is very feature rich.

I have also made some SW-decoding comparisons in the past with 32-bit Kodi and 32/64-bit MPC-BE. With the same quite bitrate heavy HEVC-file the CPU-load on 64-bit MPC-BE was about 35%, in 32-bit MPC-BE 55% and with Kodi, which has only 32-bit version (in it's basic form), the CPU-load was about 75%. As the 64-bit Windows 10 media player is also quite efficient in this area, the CPU is able to do the decoding work without dropped frames. But clearly this is not the strongest point of Kodi in Windows-platform.

Only speculating but in theory, this special version of Kodi with DSPlayer might give some extra boost also in SW-decoding with the directshow-implementation, especially with 64-bit versions of LAV-filters.

EDIT: You can toggle extra information on screen during the playing with O-key (codec info) and CTRL-SHIFT-O (player debug-info), also CPU-load should be shown. Also CTRL-J will show additional MadVR-information, if used.
