I wondered if this was a significant change with a meaning yet to be revealed by BA. So I did a further search. I found that G-CPES had also been repainted towards the end of last yeat and that it no longer carried the 'BOEING 757' titles. However the 'OneWorld' logo, as seen below in these 'before and after' photos, was still present.

Of course it is possible that 'ES was repainted before 'ET and there is an unannounced significance in the dropping on the OneWorld logo on 'ET. But I guess that its absence is just an oversight. Can anyone confirm this?
