Ok, after reading a bit more thinking of going with the V-Kool V10, which doesn't have a green tint like the other V-Kool ones. Ironically it's also the most expensive one.
Some info I found here https://v-koolthailand.com/film/royal-privacy-package-vk10/ but also based on local forums.
This video has ceramic on the left and vk10 on the right
Apparently biggest downside is some weaker GPS signal in tunnels or under highways, and it can block some tollway fast pass payment stuff, but for that you can add a small hole. I'm not using that so should be ok.
It seems V-Kool is now mainly used in Asian and very hot countries like UAE. Also lots of supercars seem to use it.
Thank you about the hint about the brownish tint on 3M Crystalline, that influenced my decision!
