is the Switch 2 screen changing or not?

[Otter]

The screen is changing, just not necessarily attached to that revision.

But also semantics wise a new screen doesn't have new functionality. Fir example some of the battery replacement hold slightly less charge or weight different (Nintendo listed in full on their site) but none of that counts as "new functionality"

I would wait a little while, I didn't think I would notice the screen thing but the Ghosting was immediately visible to me and actually makes me not enjoy handheld mode as much
