The main problem is there is still no agreed standard for 4K transmission. The broadcasters have all been working on 8K, which has an agreed track to and timescale for its standards. 4K only exists because the market for 3D TVs ran out and the display manufacturers needed a new gimmick, but 8K isn't ready.
Without standards in place, there's no guarantee that kit bought today will be capable of receiving 4K broadcasts next week, let alone when actual transmissions start. The current services are all reliant on proprietary solutions and configurations (fine when you're in control of the whole signal path, not when you want to ensure interoperability).

Confirmation in this article that Olympic Breakfast will come from the BBC Sport Centre in Salford and not from Rio.
Also the suggestion that the 9.15 am 'replay' programme on BBC Two will be a straight repeat of the overnight BBC One show as opposed to a re-packaged highlights programme. I'd assume it'll be an edited version of 10.45pm-4.00am.

It's presumably a test transmission for the BBC/NHK Hybrid Log Gamma HDR system (as it is flagged HLG) ?
Probably aimed at a symposium or convention to demonstrate it's suitability as a live broadcast format - working to both SDR and HDR receivers?
The BBC have demoed HDR and SDR displays fed by HLG signals in local tests - so DVB-S2 stuff makes sense.

The BBC are currently testing UHD on Astra 19.2, so there's a bit of spare cash floating around.

There is a UHD1 DVB standard kit of parts isn't there - just as there are SD and HD kits of parts (you can chose whether you use MPEG2, H264, H265 for video, MP2, AC3, AAC etc. for audio etc.) This is based around 2160/50p SDR in Europe?
HDR and 100/120p are likely to be later updates?

I think there is one that's floating around on the EBU website as an initial standard but doesn't take into account HDR and other improvements - can't find it right now.
