Interestingly, Apple covers more than sRGB, their panels are now being set to the broader DCI-P3 gamut. Whereas these laptops (at least in 2019) were slightly less than the sRGB gamut on testing. Except for the surface book,

I got a 2019 Dell Precision 5540 with an UHD OLED, 3.840 x 2.160 and have 100% DCI-P3. And i think many other OLED Screens have it too.

When i configured the Laptop i could choose from these options:

FHD IGZO4, 1.920 x 1.080, 100% sRGB

UHD IGZO4, 3.840 x 2.160, 100% AdobeRGB Touch

UHD OLED, 3.840 x 2.160, 100% DCI-P3

Almost no displays get 100% when tested for gamut coverage. I'm not really sure why, I think it's some testing artefact. At this point (around 99% sRGB) what you should be looking at is coverage in larger gamuts (here 84.8% AdobeRGB).
