Not quite sure what your definition of a premium domain is, compared to ordinary. 29K to 37K for a domain is just crazy for a new launch of a gTLD. Not many in their right mind would pay that kind of money for cell.shop IMO. At least not a domainer and this is a domainer driven forum BTW.
I see you have cell.shop for $29,113.77 USD. Maybe if the register's, such as you and others would refuse to carry their product on your site they might come back down to earth, not sure and probably not.
Now let's look further at how this probably works, west.xyz at $29K plus, Godaddy at almost 35K and 101domain at 37K plus. It appears to me you're making some big back end money if these sale's happen, it's different pricing on every site.
Example: Cell.shop from the registry, lets say is 25k to you, west marks it up to 29K and so you make a residual on the markup right? Whats that 4k when registered and an additional 4k each time it's renewed?
Sorry for the derail everyone but when a register chimes in as says, well we're cheaper then it's time to dig a bit deeper and figure out why. West is just not jacking up the price as much as the others, not making as much on the back end IMO.
It's a shame the registers are supporting this type of activity but it's obvious they're making some great residual income if the sale happens and this is shown with how they can price structure differently.
Total derail// sorry.
