Line item discount or net price

I’m trying to get the line item discount or the price without the discount. I can get the full price with:
$order->get_line_total( $item );

this is the loop:

private function get_legacy_one_row_per_line_item( $order_data, WC_Order $order ) {
		$data = array();
		foreach ( $order->get_items() as $_ => $item ) {

but i can’t find any function that gives just the discount for each product or the final price for each product – just the total discount for all products, and I need it individually

Any help will be greatly appreciated. Thank you
