Looks rather like the result of spot metering off the bloom. If you really did matrix meter it, that's a bad result.
Editing to add: Len Shepherd linked this review which suggests some metering funnies in matrix mode. Perhaps there will be a firmware update in the not-so-distant future if a few more people report similar problems.
