Welcome @SMO8765, to the community!
The worldwide community is a place for mutual help between users of devices from STMicroelectronics. Since your question is not a general technical question, it would be better addressed to the personal Online Support OLS.
But I can answer you the following:
- L9788TR indeed has the marking 0D273.
- The above-mentioned OLS can determine whether the goods are original if the labels are intact and legible. Since in your case both the Bulk ID and the Trace Code have been made partially illegible, this is no longer possible. Therefore, please contact the source of your devices, as they are the only ones who can provide information on this - if they want to at all.
Good luck!
Regards
