When watching certain 4K movies on my LG TV (UA7000), it doesn't transcode, it remuxes. Apparently, while the video and audio streams are compatible, the container isn't... but so far it only seems to be movies showing 4K HEVC Dolby Vision Profile 8.1 (HDR10), while 4K HEVC HDR movies don't seem to have this problem. I may have a a misunderstanding about how things like this are done, but these are movies that are ripped and transcoded to x265 for storage the same way. I don't understand how MKV can be an incompatible container format.
I also have a sneaking suspicion that this remuxing occasionally causes issues with audio sync because the audio tends to be a little delayed and needs a little twitch of the delay slider to reset it, and it's only been on these Dolby Vision-labeled 4Ks.
