Anyone know where's the SauceSource Direct button on Mi phone ya?

Mine was different, no AI image engine.
Color scheme I always set Automatic > Warm, I remember read about gsmarena test this mode gets something average DeltaE 2.4, default one is bluish
Don't have original selection also

Seek advice from the experienced AV players here for the following:

I am looking to upgrade my AV set up to Atmos, from 5.0 channel old school Dolby surround / prologic/ DTS/DD. So I have a set of 5 speakers already in place.

I recently acquired a Denon X4300H, ultimately I may upgrade all the way to 11.0 (no sub for now). My question is below if anyone can give some ideas:

1. Now I have 5.0 speaker set up, to calibrate the denon, from what I read, I should set the front LCR channel to 0db, then fine tune the surround by ears, before using the Audyssey to fine tune, is that a correct sequence?

2. One pair of surround back speakers are on the way (imported from China, just a typical stereo speakers) which I will set up as rear surround, most likely to be set as Rear Height in view of the pre-existing wiring in place.

3. Another 4 Ceiling speakers will be imported from China too, obviously it will be used for ceiling set up unless the situation demand, I can mod it with a DIY casing as Front height and Surround Height.

4. All the above is because I have two options: either I can use all speakers to set up pure Atmos (which use 4 ceilings) or Auro-3D, which uses 2 Front Height and 2 Surround Heights.  My question is, from your own experience, it is worth setting up Auro-3D speakers location for BOTH Atmos and Auro? It can be done by setting the rear as rear height for Denon.

Or I should just focus on Atmos alone. I need to pay extra to download Auro-3D firmware to allow Auro playback.

Finally, I have Mi Box S as Kodi playback, now can't really do passthrough for Atmos etc, so any other media box should I change to, eg. Mecool KM2, or others. Any other box I should consider?

Thank you all for advice.
