I think so. For the Brits, the war was a sideshow of the greater war with Napoleon. With his defeat at Waterloo, they accepted the US with the Louisiana Purchase added. Britain, however, did not really stop interference with the US until the 1870’s when the united Germany became their chief rival.
Great Britain must have been sorely tempted to intervene in the US Civil War but feared extreme blowback if they backed a losing cause.
