On iOS devices, the template chooser takes up most of the screen. On Mac, it's a tiny little modal dialog box that screams "Mac Catalyst afterthought".

And across iPhone/iPad/Mac, the thumbnails previews for each template are so faint that they all look like uniform white/yellow/black rectangles. They're only really discernible on iPad, but barely at that.

It's a minor nag for me, but objectively, it's careless user-hostility for those with vision impairments. I'd be a lot more incensed about this if I had the vision of my future middle-aged self.
