Tonight BTS are running a 2018 Moto GP review (starting shortly at 1930) the bizarre thing is this is being shown in 4K, whereas afaik Zero 4K Moto GP coverage has been run on the service this year. I hope that the action shown is indeed in 4K and that there's no upscaling.
Other than the 2015 British GP, I don't think any races have been produced in UHD.
The location looks rather nice, but does suffer from a bit of a rumbling noise every five minutes or so
- they're directly beneath the East London Line.
