Yes. It's not using any native UI widgets or UI code, but drawing everything itself using the lowest level API it can get, which I guess on iOS is Metal (and something for input). This means that the look and feel and the behavior and accessibility features will not match those of other apps (which do use the native toolkits), or the Flutter team will have to do a lot of reverse engineering and re-implementation to match that on each platform.

Currently, Flutter targets OpenGL ES on iOS which is less than ideal.

"We were discussing this in today's Triage meeting. Our current plan is to turn Metal on soon. This will increase the size of our engine by ~200KB. We can eventually reduce this by removing the OpenGL code but (a) that would drop support for <iOS10, which we don't want to do anytime soon (Skia only does Metal from iOS10), and (b) would require some work from the Skia team (OpenGL can't currently be removed from the codebase)."

Seems like it will be solved 'soon'

I am really curious why you are concerned at all about supporting iOS 9 (and lower?) at this point. That's a tiny, tiny fraction of worldwide iOS users. Probably not more than 1%. How many people are creating apps in Flutter that need to target that far back, and that user base?
