There is no such a thing like accurate or artistic colors. They are all artistic. Accuracy is just to make sure they look the same between devices, yet look is different even between best grade 1 monitors, so...
Standards are needed for sure, but whole accuracy is just another hype.
Each technology has its "look" and even if monitor is calibrated to perfection it may still look different than other one also calibrated to perfection (Dolby PRM vs Sony X300). Which one is correct ? (not going to mention about cinema).
On top of any calibration it's all subjective as each person will see slightly differently.
Industry focuses on "deltas", but this is just half of the story. Trying to get them <3, <1 etc. is really not the biggest issues. At some point it's just good enough and if average is 0.6 or 1.2 is really meaningless, because you have things like coating, angles, blooming, uniformity, near black banding, burning issue, color volume etc. These are more important than whole color deltas today.
You really have to think what is worse- having eg. blooming effect or monitor which can reach 700 nits instead of 1000 nits. Do you want one which shows visible screen uniformity issues or one which is uniform, but have near black level issue?
Match your monitor to your projects needs and target audience. Know your monitor weak points and learn how to work around them. You can still get an Oscar for your movie
Leave 30K monitors to Hollywood.
So good monitor is not the one with great deltas, but one which doesn't shift far from important parameters and in the same time doesn't exhibits prohibitive issues in other areas than color or gamma tracking, eg. very visible screen uniformity issues.
Funny enough "people" have started to ask important questions, like why movies are graded "so dark", for conditions which are about never met at home environment ? Maybe it's time to wake up and start delivering content for people, not for quite often "artificial specs". Today's TVs can deliver quite good quality. Maybe time to make a use of it. Cinema grade should be for cinema and for "home usage" (BDs, streaming etc.) there should be tweaked grade which really takes into account condition which those movies are watched in (not some perfect, unrealistic scenario). Those things are more important than fact if movie was grade on monitor with color delta at 0.6 or 2
