Update after getting my DTV in Jakarta (soft power):

After getting the visa I spent a few days off in a third country. Entered Thailand yesterday through Suvarnarbhumi airport. I gave a small bow to the immigration officer, greeted him in Thai (one of the six or seven things I can do with Thai language), gave him my passport and the A6-size copy of my printed DTV visa (plastified) by using my two hands. All the above at once, as if I was the new ambassador presenting my credentials. The officer looked at my plastified copy of the visa, said "wow" (not sure if in admiration, or as a soft form of irony) , and after searching for the right set of stamps gave me my well deserved 180 days. Well, not sure if well deserved, but I paid quite a bit for it, including logistics. Anyway, that's it. 🤗
