Yes, the QTR_ICC is too dark for my taste. The PPE-ICC is better. I fine tuned it a bit more with an adjustment curve in PPEv2. I’ll make a screenshot to show you what that looks like tomorrow. I’m done for tonight.
Here’s the PPE_ICC from your lin2.quad:

I can’t do this directly to the quad without making a curve adjustment that mimics the ICC shape. I’m too tired tonight so I’ll do that tomorrow too – the screenshot will show what it looks like in PPEv2.
