Agree. Wide gamut and HDR is janky as hell on Windows. I have multi-mon with one SDR and one HDR and that plays havoc with things. But even Microsoft apps aren't updated. I'm pretty certain even Explorer still doesn't support HDR or wide gamut for thumbnails so everything looks either under or oversaturated in the previews. If you open stuff in the default Photos app there is a "flash of content" where it displays it in the wrong profile before it maps it to the correct one, too.
