I could be wrong but ass and pgs are image based and are "burned" because that's the only way to make them compatible. Burning requires transcoding, end of story.

Well crap, maybe Plex just doesn't like them then
Oh ok, that sucks :(
I wonder how streaming services offer the ASS-like (hehe) subs without the burning delays.
That is a very interesting title if you don't realize what community it's posted in
My Apple TV 4K will play PGS without burning in
Dang, I just realized my FireTV does PGS without burning. Why do people always add embedded ASS subs if they require burningggg?
Anything Android-based using the builtin Exoplayer (Google's open-source AOSP media player of choice for Android) will need transcoding since Exo doesn't support styled subtitles fully.

Feel free to echo your frustration there, Google is unlikely to care otherwise I'm afraid.
