Does the Luma “Pro” Dome require In-App purchases? – Lumu Light Meter Review

The app is really nice! I am ready to purchase a dome and would like to know if the Luma Pro dome requires additional in-app purchases to “unlock” the pro features. Are the in app purchases merely upgrade options for the lower priced units? The pro model seems to have everything unlocked at $499 when combined with the free app, since it’s the only one without this flag: * If necessary, additional modes can be unlocked directly from the app after purchasing this model. Do all three domes share the same hardware, upgraded by the app? I want all of the pro features, and would like to know the final cost to unlock all features. Thanks!
