Mmmmmm...
I think I'll call retentions to see what they can do.
There are various posts in topics in the community which do not rate the service.
I'm picking up that even though the service can be labelled UHD there isn't much, if any, HDR or superior sound qualities such as Dolby Atmos.
So far I don't think any broadcast has initiated the genuine UHD Picture settings on my LG TV, although BT UHD does sometimes broadcast in Dolby Atmos. Iplayer does (HLG)
I do think that after I upgraded my V6 to 360 the upscaled signal output to my TV was improved, so it's not all doom and gloom,
Thanks for all the info though
