there is another differences between Apple monitors vs the rest. - standard and peak brightness[1]. All of them are less bright, than Apple's monitors. I'd really wanna know why.

MSI - 1400 nits, LG - 1250 nits, Apple - 2000 nits. That's peak brightness, standard brightness isn't even mentioned, except for Apple one. Is it just cooling or something more?

Those are down to backlight technology, which (usually) is independent of the LCD panel itself. With LCDs, though, it's a fine line as extremely bright backlights can lead to bad bloom.
