4K Blu‑ray remains the premier way to experience movies at home, delivering unmatched picture clarity and uncompressed audio that lets your TV and sound system truly shine. Since I began testing 4K Blu‑ray for TechRadar in November 2024 as part of the Blu‑ray Bounty, my appreciation for the format has deepened, turning me from a casual viewer into a dedicated collector. 4K Blu‑ray also serves as a benchmark in my AV testing, pushing the limits of visual and sound performance.

Based on the 1967 animated series, the film follows Speed Racer, a talented driver who honors his late brother’s legacy while battling corporate rivals. The story showcases a young hero who chooses family over fame, delivering high‑octane races and heartfelt moments.
From the moment I powered up Speed Racer, the sheer brilliance of its colors practically exploded on screen. Bold, saturated hues constantly test a television’s color reproduction, making every frame a feast for the eyes. Scenes of the Racer family sharing breakfast after the opening race highlight bright orange walls, green furnishings and pink details that pop with vivid intensity. Even costumes appear more oversaturated compared to earlier viewings on an LG G6 OLED, underscoring the disc’s ability to push peak HDR brightness.

Of course, the racetrack itself offers a cascade of neon advertisements, candy‑colored outfits and intricately designed car liveries. When a TV can deliver strong HDR peak brightness, these highlights become dazzling accents that truly dazzle. The disc includes Dolby Vision support, so if your display is compatible, you’ll notice an extra layer of vibrancy that elevates the overall experience. This release is a reference‑quality showcase for anyone seeking the best 4K Blu‑ray color performance.

The sequel to the 2023 blockbuster reunites Mario, Luigi, Peach, Yoshi and Toad as they race to rescue Princess Rosalina from Bowser Jr. With a star‑studded voice cast featuring Chris Pratt, Anya‑Taylor Joy, Charlie Day and Jack Black, the adventure leans heavily on visual storytelling.
The opening sequence, filled with a kaleidoscope of Lumas in red, green, blue and gold, immediately tests a screen’s color accuracy. Those vivid hues, combined with the film’s crisp textures, provide a perfect playground for evaluating color performance. Mario and Luigi’s blue‑green overalls offer a more restrained, lifelike palette that balances the film’s overall saturation. Space‑filled vistas burst with pink, purple and blue tones that feel both richly saturated and naturally rendered. Fire effects gain a realistic sparkle when displayed on a screen with strong HDR capabilities, proving that even animated fire can look convincing when color grading is precise.

Adapted from the beloved musical, this re‑imagining of Oz’s origins follows Elphaba and Glinda as they forge an unlikely friendship at Shiz Academy. Cynthia Erivo and Ariana Grande bring the iconic roles to life with dynamic vocal performances.
During the March 2025 Blu‑ray Bounty evaluation, the disc impressed with its balanced color approach. While the world of Oz calls for lively tones, the release avoids gratuitous oversaturation, instead delivering a palette that feels both vivid and believable. Elphaba’s emerald skin appears convincing rather than cartoonish, while Glinda’s bubble‑gum pink wardrobes burst with energy yet retain a natural sheen. A frequently used test moment features Elphaba beneath a canopy of pink blossoms; on a capable TV, the pink flowers, green skin and subtle blue accents on the academy walls showcase a TV’s ability to render nuanced shades without banding. Even on displays with modest color gamut, the scene remains visually appealing, though it lacks the extra “wow” factor that a top‑tier panel can provide.

This beloved musical follows Maria, a postulant who becomes the governess for the Von Trapp family in wartime Austria. The film earned five Academy Awards, including Best Picture, and continues to captivate audiences decades later.
Testing this classic revealed how modern 4K Blu‑ray can breathe new life into older productions. Restoration work unveiled previously hidden detail, while the color palette emerged with striking clarity. A go‑to reference scene shows Maria and the children at a bustling market, where yellow, orange and red fruits practically shimmer on screen. These hues feel both vibrant and authentic, never veering into artificial territory. Expansive Austrian landscapes — lush green fields, brilliant blue skies and snow‑capped peaks — burst with depth, allowing viewers to discern individual shades of grass, water and snow. This disc stands as one of the finest examples of how 4K Blu‑ray can revitalize classic cinema through superior color reproduction.

Adapted from the 2016 novel, the film introduces Roz, a robot abandoned on a wild island who gradually adopts a gosling and learns to navigate nature. The ensemble cast includes Lupita Nyong’o, Pedro Pascal, Bill Nighy, Kit Connor and Mark Hamil.
Unlike many animated features that favor exaggerated saturation, this movie embraces a watercolor aesthetic that feels like a living painting. The 4K disc captures this delicate balance, delivering colors that are vivid yet restrained, mirroring the film’s artistic style. Early sequences where Roz first encounters the island’s flora and fauna serve as perfect color tests: emerald trees, golden fields and crystal‑clear streams showcase a TV’s ability to render subtle gradients. When Roz reaches out and touches a cluster of yellow butterflies, the screen erupts in a cascade of vivid hues that glisten on high‑performance displays. Detailed fur textures and nuanced skin tones further demonstrate the disc’s refined color grading, positioning it among the most visually arresting animated releases available on 4K Blu‑ray.
