I think a current HTPC setup (i3/i5 with GTX1060) with MadVR can have more power for better quality with NNEDDI algorithms or NG1.
But of course, we will have to properly test it with discs like Spears and Munsil 2 like you did....

To get the best PQ, i really prefer to pay 600€/700€ for some 4K Bluray Player and lift my arse from the sofa to change the disk, than built another PC...Just because PCs are not reliable enough.
How annoying is when we to watch a movie after dinner, and the dam thing is rebooting or having a major update... HTPC is not my cup of Tea....and im not english

Some of Kodi developers are really dedicated to this project, and that makes it a better product than the competition.
Kodi is also very popular because its free, good playing engine and have a fancy jukebox that works 99,9% scanning libraries.
VLC is also popular and its also free but misses the Jukebox...How popular VLC would be with some similar Kodi Jukebox ?

Some people are willing to give up some PQ and struggle for capable player just for the jukebox convenience and easy to use...and HTPCs dont really fit in easy-to-use concept IMHO...
