I can tell the difference but it's not a deal breaker and not that big of a deal IMO. I'm pretty sure if it was on the Note 10 it would cost more and people would complain even more about the price. Samsung made the display for the 7 pro but it's cheaper because it lacks other features. Next year will probably be the year Samsung moves to 90hz on all their flagships now that the tech they produced is more widely used and cost won't be as much to manufacture.
