I haven't looked exhaustively but have been into a couple of the big retail stores and looked at Dell, HP, Asus and Microsoft. I found that pretty much the only ones that gave almost perfect whites and greys were the one's with matte screens. I also find that the higher the resolution of the screen i.e. 4k or just below, almost all of them have some kind of colour cast. I'm not sure you need a laptop screen with such a high resolution. It's only a relatively small space to fill. The gaming laptops with matte screens seemed to be the best in as far as being colour correct. My hi res matte screen on my 2011 Macbook is great and that's 1680 x 1050. I wish they still manufactured them.
