Expanded Exposure Warning Options

What problem do you see this solving?

Victor from Capture One recommended I submit this as a feature request after submitting it as a bug. Currently Capture One has an 'Exposure Warning' overlay/detection, with a threshold option. The shortfall is that Exposure Warnings behave strictly on a per-channel basis. For example, a pixel tuple value of (255, 10, 35) is considered as 'clipped', when only one channel has clipped. While the is great for checking color casts in very specific lighting situations (e.g. neon lights, etc), I believe Exposure Warnings fails to capture the spirit of a strict black point/whitepoint exposure warning. And perhaps worse, it provides a false impression of over-exposure. Below is in example of that disparity (image on the right is CO's Exposure Warning with a 255 threshold, the image on the left is from a Python script I wrote which looks for black point/whitepoint clipping only). In this case, the skin flagged as 'Over Exposed' by CO appears perfectly fine:

A great solution to this problem is to allow multiple Exposure Warning overlay options. Just like how the 'Before/After' GUI icon has a dropdown to choose between preview modes (full screen or split screen), the Exposure Warning would greatly benefit from having a dropdown with at least two options: The legacy (per-channel) method, or a strict blackpoint/whitepoint method.

When was the last time you were affected by this lack of functionality, or specific tool?

Daily. I check Exposure Warning's regularly.
