I had the same problem, it appear that on the LVGROUPMETRICS structure, only bordersize is recognized, all colours have been deprecated and do nothing from win >= vista. Why why why?
Index Windows 10 ModernUI applications
Column autosize crop texts with ellipsis under High DPI devices
Cannot unselect checkbox on ObjectListView
I apologize i havent properly readed all the documentations, including the fundamental "Getting Started/Unlearn you must" (http://objectlistview.sourceforge.net/cs/gettingStarted.html#gettingstarted) where it is perfectly stated that this is not at all a drop-in replacement for a listview when a lot of boilerplate is already in place. I'll give myself another chance :)
