Hello, I have designed a Cube Resolution Comparison Guide
to visualize the difference of calibrated color points precision over various cube resolution sizes between all available hardware solutions.
For example, Dolby Monitor, the best Monitor available in the world is coming factory pre-calibrated too but they performing a new calibration when they are installing/buying it.... a Brand New Dolby needs re-calibration using 3D Look Up Table too..
For example Dolby Monitor (50.000$) has 2x 3D LUT & 4x 1D LUT Slots. The size of the 3D LUT Table is 65-Point Cube.
Ever Dolby Monitor which designed to be reference needs 3D LUT profiling to meet the tight tolerance in color errors that required for critical color reproduction for movie granding in post-production facilities.
There is a Dolby Certified Calibrator who travels around the world to visit post-production facilities to perform 3D-LUT Profiling. That calibrator from Dolby is using PhotoReseach PR
-740 and JETI 1211 for spectros.
Professional displays like Eizo ColorEdge (some hi-end models, 3D LUT capable), FSI (Flanders Scientific Inc), TVLogic, Dolby Monitors have internal memories that can store 3D LUT correction tables, there models of 2K/4K DCI projectors (Barco etc.) that have internal memories for 3D LUT Tables also.
So if reference displays that are designed to have reference performance need 3D LUT profiling imagine how off is a consumer display/projector....
Reference performance consumer displays doesn't exist, just you can't see the problems if you are measuring it with a limited number of color patches (30-50).
Good Grayscale /Gamut tracking with low dE numbers can't tell you the whole story of the accurancy of one display, for example the average Caucasian skin tone resides well away from any grey scale, or primary colour, and as such is ignored by most calibration systems.

I have created also the following spec comparison table with the complete list of the 3D LUT Boxes / Video Processors that are currently available at pro industry/consumer market.
That comparison screens shows only the device features that are useful or can be used for HT use only. More more info look here
I hope that helped.
