Avengers Assemble [4K UHD + Blu-ray] [2018] [Region Free]

I was skeptical before buying this but got it nevertheless and was completely blown away by how good this looks. Excellent video as well as audio quality. The 4K is upscaled (and not native 4K), but man how good it looks! The picture is clear and the colours are vibrant. Black levels are superb and the overall fidelity of the picture is simply beautiful. The audio is a fully immersive Dolby atmos with plenty of surround effect thrills to satisfy your theatre quality audio needs. Excellent 4K disc. Highly recommended 😊🙌
