const ConstValue seems somewhat redundant, if we always have that const prefix maybe we should make this just const Scalar(0x02): Option::<()>? Or maybe also somehow indicate that this value is invalid and a "fallback" printing was used?

Dropped ConstValue part, matching the following fall back format instead of the preceding verbose one.

Make it possible to pretty print invalid constants by introducing a fallible variant of `destructure_const` and falling back to debug formatting when it fails.
