My pixel 6 pro has much, much better GPS accuracy than my pixel 3 had.
Here is a comparison between my pixel 6 and my S.O.'s pixel 2, from a hike we did recently: https://imgur.com/a/5VibEUw
This makes it pretty obvious how much the L5 band can improve GPS. These were good conditions in general, but just looking at the bottom right portion alone shows how good L1 + L5 in a phone can get. I'm sure devices with larger antennas (bike computers, larger handheld GPS units, etc) can do even better in worse conditions as well.
