Screens are always going to be an issue with laptops - I know Macs have good accurate screens - I personally bought an XPS15 laptop - the screen is not 4k which apparently has a better range than the 1080 one I went for, but having more battery life is good, the 4k one drains quicker!
Have not looked into how accurate gaming laptops are for colour - but always a good investment to buy a colour calibrator for setting the screen to be closer to how colour and brightness should look.
The other question to ask yourself is, is this going to be a portable laptop? gaming ones can be a tad bit heavy! If you are planning to move about to coffee shops or conventions and places to work on the comic, maybe a gaming laptop might not be the best choice.
Here is my laptop spec for - Dell XPS 15 7000 Series-7590
FHD (1920 x 1080) - not a 4k screen - colour and brightness is ok? but calibrated it does the job!
16gb = plenty for graphic work for photoshop/indesign/krita/CSP etc...
512gb SD = plenty of HD space - though storing on cloud/exteral helps for large graphic stuff
9th Generation Intel(R) Core(TM) i7-9750H (12MB
Cache, up to 4.5 GHz, 6 cores) - its fast, but bought this for video/3D stuff as well!
NVIDIA(R) GeForce(R) GTX 1650 4GB GDDR5 - pretty good card but not bought this for gaming so for production stuff it'll serve you well
This laptop also looks slim and is not too heavy - get almost 8hours with this on CSP in coffee shops - and using the XP Artist 12, the laptop can power the screen tablet
Hope this helps!
