In Farbfeld, pattern resolution is not done while converting, but while compressing the image. For example, farbfeld always stores the alpha-channel, even if the image doesn’t have alpha-variation. This may sound like a big waste at first, but as soon as you compress an image of this kind, the compression-algorithm (e.g. bz2) recognizes the pattern that every 48 bits the 16 bits store the same information. And the compression-algorithms get better and better at this.
Displays with 80-85% of Rec.2020 this year, but they cost $1800-$2200 for 27"-32".
10-bit and 12-bits per color channel depending on the technology (image buffers have 16-bits per color channel, either 16-bit unorm or 16-bit floating point for HDR rendering).
So granted that money is not a barrier, what would you prefer of the following?
