Amazon HD / Ultra HD - BluOS controller – Das Bluesound Support Team

Hopefully a quick fix for this one!

I've just sub'd to Amazon Music HD -

On my IOS BluOS (4.2.2) app it shows "Music" Ultra HD on certain tracks - perfect.

On my Windows BluOS (4.2.1 - latest available download) app it only shows "Music" no Ultra HD - not perfect.

Same home network, devices right next to each other, both showing ~500Mbps download speeds, both going to the same Node 2i.

I guess it's a setting somewhere but where?!

EDIT: just checked on the DAC and they are both the same bit rate so it looks like it may just be a display thing.
