ACES - Lumetri Color does not add values over 1.0

Question

When working with ACES, using Lumetri color does not increase the bright values over 1.0 except only with Whites in Basic Correction.

Example of using Curves from Lumetri

When using default Curves effect

You can see how default curves the value in info panel goes to 25.5 while the same thing with Lumetri stays at 1.0

The only setting in Lumetri that will go over 1 is when increasing Whites, but it only goes to ~1.5

@Paul Uu Hm... Perhaps I expected Lumetri to work like Nuke's grade and color correct nodes. But it is weird that regular curves work one way, and Lumetri curves work differently. The way Lumetri does it is basically how it works in 8 and 16bit workflows. Essentially, if I want to composite elements, it is impossible to use Lumetri to match values.

As for use case, we had footage that was converted in ACES and a lot of values were over 1 (it was mostly snowy footage). So Lumetri seemed like an easy "all in one" effect that works in 32bit and could help composite elements easily. AE in general is really lacking in that regard as most effects still don't have 32bit support and ACES is only 32bit.
