I was informed a couple of years ago by a good source that none of the ex-FCA 767's are going to be repainted as they are all due to (eventually) be replaced by the 787 - they are also older than the TOM airframes.
G-DBLA & G-PJLO are leased from a different company and were due to be "retired" some time ago, but the leases have been extended due to the delays delivering the Dreamliner. This is also why they are the only two that have not been fitted with winglets.
