5.1 is actually being outputted are you certain of that.
Voice search was promised at the very start of the beta 9 months ago so I think it was fair to expect that to be included.
Agreed it just means we need add by our phones like you do for Sports on Demand still it's not a big negative.
I am at work so will eagerly download this when I get home. However, in terms of DD5.1, NowTV has been using DD+ 5.1. I wonder for those of you who think you aren't getting 5.1, are you using Auto audio on the ATV4K? Auto will likely just decode the DD+5.1 to LPCM 5.1 and output it as PCM. If you are on Manual Audio > DD 5.1 in the ATV4K settings like myself I would think you would see the DD5.1 on your audio devices?
Also make sure you select the surround format for audio in the NowTV App boost pass settings page.
Live movies are badged as Stereo. All Movies on demand are badged as 5.1. Makes no difference, all movies are steaming as 2 channel stereo - irrespective of changing sound settings in the Settings app.
It's as per NowTVs own advertising - no 5.1 through AppleTV.
