I definitely get that - I think in settings where that richness and depth is a priority it makes sense to have images at their original color and brightness. However, charts and general imagery is probably fine to tune. An alternative would be something like hover/click/tap to show the full-brightness image, but that’s something of a discoverability issue unless there’s clear direction given to the user, which doesn’t fit a lot of use cases cleanly imo. A better alternative would be something configured in the browser that passes the user’s preference to the page, and an API similar to color scheme that controls image brightness in different theme modes. This is probably the best for users and developers, and least likely to be a “thing”.
