I guess you're right. Users do tell the difference! But they usually tell the difference between laggy (even 100ms IS noticeable!) and janky UI vs. snappy & smooth UI. It's not about the graphic styles and font widths and such. It's about being fast even on overloaded cheap devices in power saving mode, and don't doing anything too weird or non-sensical.
TBH I'm not sure Flutter can be fast and smooth enough for all... the market is full of crappy devices and even the good ones perform badly when their RAM is maxed out and CPU throttled bc of battery saving.
Maybe full native is the way to go. But not because of "perfect" shadows and font widths... Users care about consistency of stile inside one app, not app-style vs. system-style.
