The first morning we had this TV on the wall, my partner asked me if I'd accidentally bought a different model. The S95C we'd had before was a black mirror when off, and at 9am with the east window open it had been a black mirror reflecting our coffee table back at us. The S95D, in the same spot, looked like a piece of dark slate. No reflection of the window. No reflection of me standing there with the coffee. Whatever the matte coating is doing, it works, and it's the kind of fix that changes which rooms an OLED can live in.
The panel is a QD-OLED hitting around 1,450 nits peak HDR on small windows — measurably the brightest QD-OLED I've owned, and a real improvement over the S95C in actual content. Color is the other reason to want this thing. 100% DCI-P3 and around 90% of BT.2020, which in practice means saturated reds and greens that don't lose intensity at high brightness. Watching a nature documentary on this is the demo: foliage looks like foliage, not like a video-game shader of foliage.
The matte coating is the divisive feature and you should think hard about it before buying. It diffuses reflections across the panel instead of letting them form hotspots. In a bright room, the panel never looks like a window into another room reflecting your own. In a dim room, the diffusion is doing the same thing to your image — black levels lift slightly under any ambient light, and the inky, mirror-glossy look that OLED enthusiasts love is muted. If you watch movies in a blacked-out home theater, this is not the OLED you want. If you watch TV in a room that has windows, it might be the only OLED you want.
Gaming is fully covered: 4K at 144Hz, VRR, ALLM, the One Connect box that runs a single thin cable from a separate hub to the panel (clean wall-mount installs are a category Samsung still owns), and a solar-rechargeable remote I've never had to find batteries for. Tizen is snappy. Built-in audio is surprisingly good when wall-mounted because the panel itself contributes resonance.
The Samsung asterisk is the same one as every Samsung TV: no Dolby Vision. Samsung refuses to license it and pushes HDR10+ instead, which has roughly 5% of DV's content library. If your watching is mostly Netflix and Apple TV+, you'll see HDR but not the Dolby Vision-mastered version, and on titles with both — most prestige TV — that's a real loss. If you're a Samsung phone owner who buys movies on a Samsung TV and doesn't use Apple TV+, the omission won't bother you. If you're an Apple-ecosystem household, factor it in honestly.
The panel throttles under sustained brightness torture patterns after about twenty seconds, which is normal OLED behavior and means nothing in actual viewing. Black levels lift slightly with ambient light, which is the trade for the coating.
Verdict: Buy the S95D if your living room has windows and you've been holding out on OLED for that reason. If you watch in the dark, the Sony A95L has a more OLED-feeling picture.
