I spent the 2016/2017 TV season tracking all the warehouses on the CW for SCIENCE and can confirm all warehouses look pretty well the same.
Granted, that could be because the CW uses the same ones over and over and over and over and over.
(There are SO FRICKIN MANY warehouses on the CW.) (So many I never finished writing up my data because I COULD NOT STOMACH IT.) (But I did finish the superhero shows.) (Supergirl's Queen of the Warehouses).
