There's more than enough evidence that it CAN. However, I think it's benefit is highly dependent on skill level, and how much it's going to help, but it definitely helps. Also, this can depend on your eyes. It might not help a lot because of variances in people's eyes, so this can change from person to person. I know that I can tell the difference between gaming at 60Hz vs. 100Hz. I have a hard time much past 120Hz and being able to tell the difference. Also, I'm noticeably more accurate at higher refresh than I am at 60Hz.
From a technical standpoint, absolutely, yes. You can tell a difference, provided other factors line up. Other factor can effect the law of diminish returns to the point of it being irrelevant depending on the person.
