I would choose a matte surface to minimize reflections.
Some photographers are very particular about gamut, i.e. how large a range of colours the display can accurately render (in % of colour spaces such as sRGB and Adobe RGB).
Gamut of laptops are reported by some websites, e.g.,
https://www.notebookcheck.net/The-Best-Notebooks-with-the-Best-Displays.120541.0.htmlPersonally I think the rendering of shadows is very important as many modern displays are designed to produce a bright image and the dynamic range is not sufficient to render shadows accurately. A very bright display may be difficult to calibrate and may not be accurate for preparing images for printing.
I use an Eizo monitor on my main desktop computer for editing. My laptop isn't particularly good with regards to gamut but it's adequate for editing (with the caveat that it may not be as accurate as the separate, specialized monitor). I would say the laptop screen is intemediate after calibration.
