And now today's EastEnders is going out on Drama in a 14:9 frame pilarboxed in 4:3 in a 16:9 frame.

I guess it's likely they recieved a 14:9 copy of this episode, though that doesn't explain why it's flagged as 16:9 rather than 4:3- so the pillarboxing is there even on the SD channel and the DOG in the 16:9 area.

And of course it's still filmised and zoomed in (as evidenced by how thin the 14:9 letterboxing is).

I don't know if someone's trying to fix things and just making it even worse. Most episodes of Casualty have noticable interlace artifacts on the text on the scrolling end credits now, which wasn't the case until a couple of weeks back.
