Wrong Z depth rendering?

When rendering to the picture viewer the Z depth seems to clip to all white.
I am using v3 alpha 6.3

Here are some images to that show the issue.

What my live viewer looks like when selecting the Z "preview"
z depth render settings 3.PNG
What my Multipass render setting are

And this is the Picture viewer result. I also checked in AE and the values are clipped.

Am I missing something obvious? I have done this countless times without issues so I am really stumped.

Thanks!

Something obvious: PNG 16bit is a clipping format.
Maybe try EXR 32bit?

Thanks for asking again;) I have replied a few times recently. When rendering is linear(float buffer) pixel values is not clamped. But float-tonemapped is clamped due tonemapping as you see in LV. So when z is bigger than 1.0 it gives 1.0 for tonemapped outputs or tiff, png, psd. Use EXR, it can store these values.
