I am pretty confident you my still get a window seat once online check in opens unless everyone else has pre paid or has status

Whether you end up with an aisle or window wouldn’t fall into the compensation category under comparable transport conditions I guess , as you are still conveyed in the business class cabin in a business class seat, equally to BA Club World seat or Club Suite, or a seat change in Club Europe from aisle to window in the same cabin etc. Others may have different opinions, but I wouldn’t go down the UK/EU261 or MCOL Route on this one, unless your flight was cancelled within 14 days of course and falls into a claimable category for the cancellation
