I only dabbled in the HDR support for URP and I'm super excited for it as an enthusiast for HDR. But one thing I noticed is things looked desaturated which is an issue I've seen in some games like Elden Ring but that remedies this with a saturation slider. Usually these games let you set the saturation, probably for display variance. I think a saturation setting should be added independently of other color settings so the SDR and HDR modes can look more similar. BUT this might be an issue of my shaders not working correctly in the new version. It's just an issue I noticed.
