Unless you are doing professional work like RAW image editing, producing print, making a living on image related work, 16.7 millions of color is more than enough. in fact, wide color gamut is bad for ordinary consumer that do not know how to calibrate their screen. all your photo and web picture will be oversaturated, none of them will looks natural. can be a good thing if you are Samoled lover, the screen used on galaxy phone where everything is "out of the world".
If you care about color, please buy a color calibrator tool to properly calibrate the display. billions or trillions of color is useless if we can't control it.
I will never get Samsung monitor if they keep skimp on simple back light control and use PWM for their back light.

The back light will switch on and off when its set below 30% setting, That's about 160 cd/m2 or way above pro standard of 120 cd/m2, in other words, the monitor back light will be switching on and off ~240 times every seconds for normal brightness setting.
Most of Dell monitor do not use PWM, including U2715H.
