It's been since the new logo - the picture is much sharper as if is in 1080p on the news, Emmerdale looks better in a lot of scenes not all. I don't see much tv at the moment because of work mostly so only see about 1 hour.
if most people watch via a receiver then it's likely the receiver is set to upscale the pic and maybe adding whatever infererence can be caused inside the busy box so maybe it won't notice.
I don't have any picture scaling, except what's in the Kuro - so all changes stand out now much more than before.
