'todo.microsoft.com' domain changed to 'to-do.office.com' AND UI is WAY different (as of 9/11/18)
Ok, glad it's not just me - we started testing MS Multi-Factor Auth the same day and I was afraid something was being blocked that was affecting the appearance. It also threw me off since, as you can see from the screenshot above, changing the 'theme' of a list stay states "choose a color and a scene" where there, in fact, no more header scenes depicted on any lists. In the web version that is, the To-Do mobile app (at least the iPhone version) has not changed at all and still has the former UI and header scenes per list. Thanks for confirming.
Also, while there was no mention of either the domain change nor the UI change in the 365 Admin Message Center (where I usually go to stay abreast with changes to our tenant), I did find this on the 365 Road Map:
New design for To-Do for Web: To-Do for Web 's design is getting updated to simplify the experience and align it more closely with the other experiences inside Microsoft 365.
Estimated Release: September CY2018
Feature ID: 33018
So, I guess, there it is...
