Your “boring” is a blind persons “basically usable”. Standards exist for a reason.
I actively judge apps with non-platform-standard UIs as worse than an equivalent with a standard UI.

That covers about 90% of Hollywood's output, and the reason for that is that you want a wide audience to purchase tickets. Only people that are good at navigating new interfaces appreciate novelty. That's a niche audience, but it intersects with the gamer audience (they're good at exploring new environments).
There are enough exceptions that whatever API you are using should accomodate developers in those cases. If people want custom UIs they'll get them somehow, you putting unnecessary roadblocks in the way will only annoy developers.
Managers don't care how you do it, they just want it done.
