Make that 3 then, the Domane ALR is 200 series aluminum tubing.
To the OP. Yes, some companies to have different levels under the same model name but I've not known any to try to obscure that fact. Cannondale has 2 CAAD models but ID them as the 12 and Optimo. The cheaper Optimo is claimed to have the exact same geometry and the 12. Those are the only 2 brands I've really looked at extensively but would expect other brands such as Specialized and Giant to be the same.
