Asus ProArt PA329Q Overkill for CGI ?

Since almost no consumer device goes beyond srgb, is it overkill to get the ProArt for 1.3k€ ?
What would be an appropiate alternative with 4k ?

Do you have a graphics card with 14 bit output ?? I’ll ask you more easily, you use an NVIDIA Quadro? If you do not use a Quadro is useless, only they have an output that supports the Lut and the 14 bits.
