Custom camera profiles don9t require you to see several hundred colors

Viewing and evaluating photographic images, however, very much does.
Ask any scanner operator what they're usually asked to do. They'll
tell you they're asked to match the chrome.
Ask them how many of their requested edits make the scan match the
chrome more closely. They'll tell you basically none of 'em.
In short, you're elevating colorimetry to a role for which it was
never designed, and isn't all that well-suited. We see colors in
context, colorimeters and spectrophotometers don't. When you're
trying to match an already-rendered image, that's not a deal-breaker,
but when you're trying to render a live scene, it very often is,
particularly when the capture contains a far greater dynamic range
than you can possibly display or reproduce.
