My mistake. I honestly thought I saw it. Ok, then, yeah, they definitely should've mentioned it.
I still think this is a non issue and this forum is just looking for things to pissed at. From the notch-crisis that seems to be winding down now that people actually got to use their MacBooks, to this. No one advertises SDR brightness, because SDR content is mastered at 300 nits anyway. I really don't get it why everything is this shattering catastrophe in this place, I can only assume it's some sort of inner justification mechanism.
Still, it was my mistake, I genuinely remember seeing it in Tech Specs, so my mind must be playing tricks with me. I apologize, I should've checked before I wrote that.
It was an honest mistake. But sure, call me a liar. You're just a nice person, aren't you?
