Can you confirm if the issue is just with Kodi, or are other Android apps also not working to pass through DTS and AC3 via SDPIF/ARC ?
Could I use other Android apps to stream x265 (with DTS/AC3) from my Synology and get both video & audio to receiver without issues?
Any 3rd party app is broken for one or the other multichannel format, depending on the used format. Official Kodi in the Play Store uses IEC API. This is broken for both, Dolby and DTS. Most other apps use the RAW API which at least works for Dolby (Lollipop up to 448kbps, > Marshmallow up to 640kbps).
The only possibility to have Dolby and DTS working is by sideloading a Kodi custom build which uses the old PCM hack (so-called [Profanity removed by moderator] builds). I won't go into detail as I don't recommend using those. It might only give you some high-pitched noise which can destroy hardware or even harm your ears.

E.g does Netflix app sends the mutlichannel audio through?
Netflix uses the RAW API and a bitrate < 640kbps. So this app is safe with any firmware.
can I cast 4K via google cast?
I was able to cast in 4K even before the mentioned update. Google Cast Receiver would pick the 4K stream...
what does Sony support says? should we all open tickets?
I gave up talking to the support a long time ago. They won't understand you or forward anything to the development department.
I have much more trust in @Anonymous in that regard...
Does the Stock app allows to stream from a synology & play mkv H265 with no issues?
Stock app supports UPnP/DLNA only, but is not very good. It for example won't play MPEG-TS from the Synology certified DLNA server...
