#Dolby atmos test disc 4k 720p#
You could easily argue that there's no point going beyond 720p at a "normal viewing distance" for the "average viewer". Who defines what a "normal viewing distance" is anyway? You don't need side-by-side comparisons to see if there's color banding (posterization) or blocky artifacts in dark scenes.Īnd I find those artifacts to be the ones which tend to stand out at a distance, if anything. If anything, this really goes to show that 4K streaming has come a longgggg way, and there’s really very little reason to opt for 4K disc based media any more in regards to picture quality. The rest was preferable on Disney+ streaming Out of the 6 movies he sampled, only 1 (Empire Strikes Back) was better on HDR-10 Disc, due to the low 600nit peak brightness of that film’s HDR grading on both formats. Dark scenes generally look brighter and clearer in the Dolby Vision stream The Dolby Vision stream is able to preserve a bit more detail in bright highlights, like the sun 4K blu-ray appears slightly darker, probably because it only has one static HDR tone curve for the whole movie, compared to frame-by-frame dynamic metadata with the Dolby Vision stream In brighter sequences, specular highlights and detail look similar on both formats
Posterization in a handful of dark scenes on Dolby Vision stream More compression artifacts/macroblocking up-close on Dolby Vision stream, but unlikely to be noticed from normal viewing distance Dolby Vision stream’s Average Picture Level (APL) is slightly brighter, creating clearer shadow detail
