I just looked at the Los Angeles Thai consulate website for visa information. Early in the website they have a notice to foreigners that they have to report to immigration every 90 days. This informational notice makes no reference to visa types. It applies to all foreigners.
Later under the LTR visa, in addition to to requirements for the various types of LTR visa, they also post the BOI graphic specifically mentioning that 90 day reporting has been extended to 1 year reporting for LTR visa holders.
No other visa type, including O, OA, and DTV has any mention of modification of the 90 day reporting requirement.
The website tells you that you have to do 90 day reports. That requirement applies to every visa type (including the DTV) except the LTR where the adjustment is specifically mentioned.
Unless you can show a consulate website that says otherwise or something printed in the Royal Gazette that says otherwise then you can safely assume that DTV holders have to do 90 day reports. The first report has to be done in person.
The good news is that if you fail to do your 90 day report and get caught then you are only going to pay a 2,000 baht fine. They are not going to take your visa away or deport you.
