The G5 and S95D are the OLED flagships from LG and Samsung — each brand's best panel, best processor, and highest peak brightness. LG's G5 uses a Brightness Booster Ultimate WOLED panel with a redesigned MLA layer; Samsung's S95D is built on SDC's fourth-generation QD-OLED. At 65" both push $2,300-2,800. The specs diverge in ways that meaningfully change which buyer each TV suits.

Specs Comparison

Peak Brightness: QD-OLED's Continued Lead

Samsung's S95D reaches approximately 1,700-1,800 nits on a 10% HDR window — a figure that was impossible on any OLED two years ago. Fourth-generation QD-OLED achieves this through improved quantum-dot phosphor efficiency and a more refined blue OLED emitter layer. Real-world HDR highlights — a tungsten filament, lightning strike, or sun flare in a film — look physically more present on the S95D than on any current WOLED panel.

LG's G5 with its revised Brightness Booster Ultimate MLA layer reaches approximately 1,300-1,400 nits on the same 10% window — meaningfully above the C5's ~1,000 nits but still behind QD-OLED. LG has closed the gap considerably, but QD-OLED's structural advantage in blue-OLED-to-phosphor conversion maintains the brightness lead at peak.

On 100% full-field white — the more real-world metric for sustained bright scenes — both panels land around 200-230 nits because ABL (automatic brightness limiting) throttles both hard to protect the organic compounds. Neither TV is adequate for a sunlit room on large bright content.

Color Volume and HDR Formats

The S95D's QD-OLED panel delivers DCI-P3 color volume above 97% — colors retain saturation even at peak brightness, which standard WOLED panels cannot match. Blues in QD-OLED are exceptionally deep because the blue OLED backplane contributes directly without quantum-dot conversion loss.

The G5 supports Dolby Vision, Dolby Vision IQ, HDR10, HDR10+, and HLG. LG's Dolby Vision IQ implementation on the G5 is the most sophisticated ambient-light-adaptive HDR available in consumer TVs, using a multi-zone sensor to dynamically adjust tone mapping and color temperature as room conditions change.

Samsung's S95D supports HDR10, HDR10+, and HLG — no Dolby Vision. The majority of premium streaming HDR content is Dolby Vision mastered: Netflix, Apple TV+, Disney+, Vudu, and 4K UHD Blu-rays. On the S95D those sources render in HDR10 — technically fine, but not the dynamic, scene-by-scene tone mapping that Dolby Vision provides.

Processor, Calibration, and Out-of-Box Accuracy

LG's G5 runs the Alpha 11 Gen 2 AI processor with AI Picture Pro. LG's tone-mapping algorithm on the G5 is widely recognized as the most accurate available at the consumer level — calibration measurements from RTINGS and HDTVtest consistently show excellent Delta E scores and near-reference grayscale tracking in Filmmaker Mode without professional calibration. LG's OLED Care monitors panel usage and triggers preventive maintenance automatically.

Samsung's NQ AI Gen 2 in the S95D is capable but defaults to more aggressive sharpening and saturation enhancement that pleases in showrooms but requires calibration for reference accuracy. In Filmmaker Mode the S95D is very accurate; in default settings it over-processes. The QD-OLED panel's high color volume also means out-of-box colors can appear oversaturated before calibration.

For buyers who want closest-to-reference accuracy without professional calibration: the G5 has a measurable real-world edge.

Gaming, Connectivity, and Price

Both TVs offer four HDMI 2.1 ports at 48Gbps supporting 4K/120Hz, VRR from 40-120Hz (G5) or 48-120Hz (S95D) via FreeSync Premium Pro and G-Sync Compatible, ALLM, and input lag around 1.0-1.1ms at 4K/120Hz. Samsung's Gaming Hub adds direct Xbox Cloud Gaming, GeForce Now, and Steam Link access without a console — a meaningful convenience for cloud gamers.

The G5 ships without a stand — designed for flush wall mounting. LG sells a gallery stand accessory separately for approximately $130. The S95D includes a stand at smaller sizes and offers One Connect box cable management at larger sizes.

At 65", the G5 retails around $2,499-2,799; the S95D sits at $2,299-2,599. The S95D is typically $200-300 cheaper despite its brightness and color volume advantages. That pricing reflects Samsung's strategic positioning against LG's flagship rather than product inferiority.

The Room-Dependent Verdict

In a dark, controlled room — dedicated home theater, basement, light-managed bedroom — the S95D's QD-OLED panel is the more visually impactful display. Its higher peak brightness makes HDR highlights genuinely more dramatic, and its 97%+ DCI-P3 color volume produces more saturated, physically present color. For the best subjective dark-room cinema experience, the S95D wins.

In a normally lit living room with windows, lamps, or ceiling lights during viewing, the G5's WOLED semi-gloss surface wins on practical picture quality. The QD-OLED's glossy finish turns into a mirror under ambient light; the WOLED handles it more gracefully. Add Dolby Vision IQ dynamically adapting to that ambient light and the G5 delivers a more consistently excellent image across changing conditions.

Both TVs are objectively exceptional. The choice is between dark-room brightness drama (S95D) and bright-room consistency with Dolby Vision (G5).
