There’s a fair amount of evidence that Revelation was not just written in Greek, but in Hebrew/Aramaic-influenced Greek, as said above. But more than that, it’s “quote the Septuagint as much as you can” Greek, as was shown in 1881 by Westcott and Hort. (They edited the standard academic text of Revelation and other books, in Greek, and there’s an appendix index that shows all the references.)
The Book of Revelation is 404 verses long, and 278 of them include Septuagint OT references. When we read Revelation without a deep knowledge of the Septuagint, we catch a lot of the OT references, but not the specific Septuagint ones.
Thyine is actually one of the bits that isn’t a Septuagint reference! The whole passage is similar to Ezekiel 26 and 27, where people lament Tyre’s sacking by Nebuchadnezzar, but those chapters talk about different fragrances. Thyine was super-popular and expensive in John’s time, though; Pliny says in his Natural History that women would rather have thyine than pearls.
