I’ll try to get a screengrab later, but it appears to just have the ends chopped off so there is no letterboxing. They do this for US TV broadcasts as well, but have always used the blu-ray transfer.
Ah, I understand: the modern day equivalent of full frame, in order to appease viewers who’d complain about their 16:9 TV’s not being filled. This practice is also widespread in the UK as well.
