HDR recording colors blown out and dark V28

[strickforce]

I'm testing out the new v28 release and notice that the colors for HDR (I believe I selected the right things?) are wayyy blown out and unusable.

stream PC OBS settings:

Under the properties for 'Video Capture Device' I have:

Video Format - PO10
Color Space - Rec 2100 (PQ)
Color Range - Default

Using HD60S+

One picture is what OBS is showing, the other is what my main PC / monitor looks like. Am I missing something?

The contrast is super cranked on mine as well even just sending a standard signal over after the update. Some tweaking and color correction helped some but not enough... In 27 by default it was pretty good before when using a duplicated screen to send to the card. This is on a 4k60S+.
