background color of QTreeViewItems with windows 11 style

When setting a background color to a QTreeViewItem the color do not totally fill the cell.

there is top and bottom offset and rounded corners on first column.

in this case the QTreeWidget is difficult to read.

if we use alternate row colors, each row is right full-filled (no offset and no rounded corners)

Is it possible to fill rows in the same way when setting a background color ?
