Do you even know what CMYK is? It is used in printing (I am a prepress operator by trade) and it is not a colour standard, the standard that most CMYK printing aims for is ISO 12647/2
Tv's, phone screens ect are RGB. sRGB is a Colour space which most phone tend to target.
I’m a designer by trade. Of course I know what CMYK and RGB is. The point I am making is that digital color that can represent real world color should be the goal. Not overly saturated, hyped up color modes. That’s the point. Aim for a true representation of color.
