The date in the footer of the information guide 3901e is 12-2015 so based on that I think they will accept previous application photos. However, the photos you provide are used on your COPR I believe, or on your PR card, not sure which. So if the format has changed for that then we may have to provide new photos.
LauraMo got DM on 3rd December, so after this change to photo dimensions and she got her COPR on the 11th of December with no request for additional photos.
Have you tried contacting LVO to ask if they have sent it?
