not really an issue for most people
the majority of the display issues wont be noticed by the average consumer, unless you actively look for them.
The issues on the pixel 2 XL had been widely overblown. Many reviewers have since noted they do in fact have similar issues on other oled screens too (samsung, LG, and other devices) now that they looked have for them, they just hadn't noticed they had a 'problem' before.
Google have released their software update to address many of the reported issues, mostly down to the muted colour palette the went with, which is where this all started from.
Maybe now this this is a problem that Apple have 'acknowledged' perhaps we are all indeed just looking at it wrong.
