Having a similar experience, even with most recent upgrade to 15.4.1. For me, Lumetri is clipping everything at 100 IRE, and stops the y-axis of the graph at 100 IRE. In previous builds, with the same footage, the graph goes to 110 and I retain detail from the footage in the range from 100 to 110, which I am able to "recover" in color correction.
This issue is essentially clamping the footage destructively, with no apparent way to access/recover those lost details in the Premiere color correction workflow.
Has anyone found a solution or explanation to this yet?
