Yep, no physical copy for you.
Even if you have a Mog Station account, are using the official launcher, etc.
It doesn't change a damn thing, you have to get the Steam version of Heavensward.

They will most likely sell the digital CE, but I'm afraid that you won't have a shiny dragon.

The only way would be to buy the physical CE for yourself, buy the Steam digital CE to match your account, and then sell the physical CE code to someone else at the price of the digital CE.
