Seems so. Just got this from Qobuz CS:
Dear Customer,
As you may know, Qobuz has just introduced the Studio Premier subscription in the USA for $ 14.99.
Unfortunately, this subscription is not yet available on the service in other countries. However, this is a temporary situation due to negotiations that are still progress with the rights holders in other countries.
Qobuz is working tirelessly to synchronize our offers across the world. The Studio Premier plan will be available to our users in other countries soon.
Thank you for your interest in Qobuz
