I recently started collecting 4K UHD Blu-Rays since I got a Samsung Q990c.

The most obvious difference to me is the audio. Though the discs do look better than say Netflix 4K, the audio is way better on my particular setup.

I do wonder if streaming is really the same "atmos" as a 4K Blu-Ray. From my experience there must be some serious compression or misrepresentation.

Will be interested in trying FlexConnect with and without Blu-Ray once it's available for me (though not sure it would be better than my current setup).

You are correct that streaming atmos is different. Blu-rays deliver audio using the Dolby TrueHD audio codec, which is a lossless codec whose streams average 6 mbps, but can peak up to 18 mbps. Streaming services use Dolby Digital Plus to deliver dolby atmos content, which is typically encoded at 768 kbps.
