Definitely a non-traditional day of the week to premiere a cartoon, but, if said cartoon is going to be served mostly via on-demand streaming services and/or video platforms such as YouTube, then the traditional "Saturday Morning" air schedule may not be necessary, especially since a lot of families don't watch cable TV anymore due to the wide availability and reliability of streaming services nowadays
That's quite a big "if," though, since it's already scheduled for Treehouse on the 21st, which is a Sunday. I guess some of its target demographic may not know how to use the internet.
