They both have much higher tap latency due to the Android graphics stack. The difference in drag/scroll latency feels even higher, but I don't know how to measure that quantitatively without special equipment.
Example of ROG Phone II results:
Kernel module, display running at 60 Hz: 10 ms
Android, 120 Hz display: 32 ms
Flutter, 120 Hz display: 30 ms
They're only this close because Android gets 2x the refresh rate here, but it's still 3x slower.

Those Pixel 5 measurements are impressive if it’s a stock Android app.
Thank you!
