I have a modest 5.1 (non atmos) setup, you don't need to be at the bleeding edge to have a nice sound system nowadays.
Tech like the Samsung Q soundbar have been discussed in the past here, some pan it as a gimmick but understanding how sound works (reflection, timing to ears, etc) this is certainly a reasonable path forward and one that, with lower initial overall cost (time/effort/money) for the listener, may ensure more people get into the surround space at home. I've not yet personally heard a system using this 'phantom' atmos tech, but there's plenty of reviewers in the past couple years that give it a tepid thumbs up. Nothing beats dedicated speakers in the right positions, but at the cost of entry (time/effort/money) these are a viable option. "Better than nothing" as they say.
GOS jokes not about collecting surround releases (and/or dumping money into that 'proper' atmos setup). There's a lot of physical releases in 5.1 (and Quad/4.0) that may never see an Atmos remix.
