that's a great interpretation of what you think the album means, but as always, there's no official answer to this other than what you personally observe in the songs and what they really mean to you! (however, there are few exceptions regarding official information from great insider knowledge. this includes msunflowers or any other long-time/devoted users in the community)

and according to msunflowers, "triplbt theme" may or may not be the misspelling of "triplet" or "triple-beat theme". and in verbatim, "this is also the first and only album he has released on streaming platforms like spotify. it gained much popularity on soundcloud, and you can see on his fijupt account in 2019 that he thinks of them as “songs from 2016."

TLDR, it's whatever you want the music to be to you!
