One way you can tell this nostalgic quest is a little silly is by the fact that new indie pixel art games are mostly excluded from this nitpicking.
I lived through the CRT > LCD transition and the only downside to LCDs at the time was A) resolution interpolation, and B) motion blur. (Both of these issues have since been addressed.)
When CRTs were the norm we were never satisfied with their crispness. We always yearned for more clarity and a smaller dot pitch. When you saw a game displayed on a sharp monitor the improvement was both obvious and somewhat amazing. But now we've finally got what we want in the form of high-resolution LCDs and OLEDs and we're trying hard to find new faults to be fixed, haha.
I am a bit of a hypocrite: I like a good CRT overlay on my retro games. It invokes a feeling. But I won't say it's objectively better.
