As someone already suggested, this one does look like a beadblasted ti frame to me.
Can you show us a picture of your stamped serial number?
Stamped means metal is displaced as the indents form the number. You can see in that photo - metal was displaced. That proves nothing, but as pointed out, I normally see Ti cut/or engraved or etched - not stamped.
Being a Look - maybe production was high enough they stamped.
