For the immediate time being, if you want to see unclamped values, you will need to look at a "render" in a 2D viewport (be it rendering to mplay, taking a Render Gallery snapshot, using a Live Render, etc).

If you can send us a hip file (ideally via a bug), we can have a look. There are a number of places where things could be going wrong that results in what you're seeing.

Looking at the internal log, the issue should have been resolved in 21.0.497. If it's still happening, that bug should be reopened (or a new one created).
