To revive this topic as I'm back home for now, so I've had a chance to test the ATV4k and HDMI input on the CXUHD.
Test Case Setup:
1. ATV4k plugged into CA CXUHD HDMI In
2. HDMI 1 out goes to Sony 940E
3. HDMI 2 out goes to my pre/pro (which can do DTS Master HD or Dolby True HD max, no Atmos)
Test source: ATV Netflix app w/ sound settings set to 'best available'.
Audio - using the Info feature on the CXUHD, sound was sent/passed through as LPCM, either 5.1 (most of the test shows I've tried) or LPCM 7.1 for Dolby Atmos shows
Video - max resolution was 4K and HDR (no Low Latency Dolby Vision for Sony TVs obviously).
Hence, for top resolution shows like Altered Carbon, best I could get using the CXUHD as an HDMI switch/audio extractor was LPCM 7.1 audio and HDR video.
All looked and sounded good, however, the Netflix menu WAS SLUGGISH though, so operating it was a little of a pain (the show previews would seriously stutter), but once the show started, all was good to go.
