I have Royal kinam 2.0, White Kinam, Brunei Kinam, Kyara Ketone, Kyara de Kalbar, and AA Royal Chen Xiang. Plus some authentic Kyara(Green and black) chips that I have heated.
Each has kinam elements but none really smell identical to a kyara chip of low heat, but they have many similarities. The other thing to understand is that it is not always about the exact scent but more so about the overall qualitative experience and which aspect of the kyara spectrum the oil is focusing on. Kyara itself is not a fixed or fully defined thing, it’s more of a spectrum and qualitative experience.
Out of these oils I would say AA Royal Chen xiang is the most straight up kynam aroma and experience. All of the others have kinam elements through the lens of the region, China, Borneo, Sri Lanka, etc.
Lastly in my opinion aroma is secondary and qualitative experience is primary, ie how does it make me feel, what is the full experience, etc.
