For sure, but he isn't explicit about it either. I thought he's talking about tech nerds who pays attention to every little details (ones who 120 hz screen can make significant difference. That kind of guys). That got me looked at my X screen for minutes and I thought "What the hell? Where is this flickering he's talking about?"Obviously the OP didn’t make a blanket statement that everyone is having issues with OLED. It’s right there in the original post.
If he just started his post with "I know it might not affect all of you but it affects me.." then his point will be very clear and we can understand where he's coming from more clearly.
