Is there any 15" notebook PC with a good 4K screen?

retina macbook pros, which have 5k displays and are also are wide gamut
dci-p3. the 13" versions have 4k displays, also a good choice.

2880-by-1800 native resolution is not a 5K display. Check again.

2880 x 1800 = 5184000

there are two ways to classify displays, one is the total number of
pixels (for the above, 5.2k) and the other is the horizontal dimension,
5120 x 2880, which would be 14745600 total pixels.

https://en.wikipedia.org/wiki/5K_resolution
"5K resolution refers to display formats with a horizontal
resolution of about 5,000 pixels."

So you have been caught trying to cheat.
