I would say remember its the receiver that needs to support Atmos, not the player. The Atmos data is matrixed into the regular TrueHD stream, much like Pro Logic II was encoded into a stereo signal back in the day. Your receiver will then decode the stream and direct the audio based on whichever speaker setup you have.
All you need is a player that will send the raw audio signal to your receiver, which to be honest has been a standard feature for Bluray players for awhile. The last time I remember it being an issue was the first HD-DVD players...
The Samsung player will pass every audio format needed. Obviously the receiver has to handle.
Ironically the material that will gain the most out of a UHD remaster is stuff that was shot long before the dawn of 4K digital cinematography, especially material with limited or no use of CGI. The UHD BD Ghostbusters releases are supposed to be great, Labyrinth is getting a UHD release in September. A lot of recent standard BD releases were accompanied by new 4K remasters of the original elements for posterity and a better quality downsample to 1080p, so there should be much less work involved to push out UHD discs (other than mixing for HDR etc.). Here's to hoping that a UHD BD drive in a mass market device pushes adoption of the format.
As an aside I think it's hilarious that we could potentially see mind blowing 4K remasters of the original unaltered Star Wars trilogy while George Lucas with all his forward technological thinking filmed episodes 2 and 3 entirely with primitive 1080p digital cinema cameras.
Ghostbusters I and II both are mind-blowingly great on UHD BRD.
And you're right, some recent stuff will look great, but it's shocking how many films digital effects are done at just 1080p/2k. You can't even really just blame Lucas, even Force Awakens, despite being shot on 35mm, has 2k special effects.
That said, tons of stuff from the 80s and earlier are going to look AMAZING with UHD versions.
