Even the early 240 power mirrors (up to 85) and all 240 mirrors 86-93 have a different angle on the base for LHD and RHD...due to where the driver sits and angle of view...and range of adjustability in the mirror mechanism. So yes, you’ve unfortunately discovered something that’s common on most cars.
Regarding the Arabic writing on the mirror, that is odd. If it’s quite lightweight it’s possible the mirror is chrome plated plastic. I know some cars have that. Not as scratch-resistant as glass but maybe it was used in markets where ice and ice scrapers were not an issue...
