I was going to say it was because that was what the BBC thought people 
wanted for watching Eastenders, although curiously not all sporting events.

Then I looked at --info for episode 4 of series 3 of Hinterland, b08s3f2s. 
It has hlshd1 and hlshd2 modes.  How are you selecting the mode?  Try
--tvmode=hlshd
Sometimes HD modes appear later than other modes.
