UI screen space overlay is washed out in HDRP

So I switched to HDRP using the upgrade guide. First to 7.18 then to 7.3.1 in both versions my UI text etc (screen space overlay) gets washed out. It is not super washed out but it is noticeable. Any ideas on how to fix this?

Reds end up looking pink.

Ok I think I fixed this. It seems to be a combination of background colors and text colors. Somehow the text was not set to full black after upgrade.

Nope still not fixed the images are still washed out the text is fixed. I generate a Ui image at runtime. Maybe some kind of HDR is messing it up?

Hi could you show some picture?
I will expect it is related to exposure / tonemap. But UI should be draw in world, they should be draw after postprocess. Need more information. thanks

Did you ever get an answer to this? I’ve just upgraded to HDRP and all the UI objects are washed out and faded.
