While it’s tempting to jump to the conclusion that Dolby Vision was superior to HDR10 in terms of end-user HDR experience,
we needed to point out that the LG 55E6 OLED’s HDR10 rendition was hampered by relatively low peak brightness and substandard tone-mapping. All we could surmise from our comparison were as follows:
- Dolby Vision delivered a superior HDR image compared with HDR10 4K Blu-ray on the LG OLED55E6, displaying less highlight clipping and more accurate colours;
- The most effective method to recover the blown-out highlights in Ultra HD Blu-ray movies on the LG E6 was by lowering the [Contrast] on the source player; and
- A top-end 4K HDR LED LCD TV with high peak brightness and correct tone-mapping (for example the Samsung UE65KS9500) could present HDR10 UHD Blu-ray films in a manner that’s not inferior to Dolby Vision.
In other words, Dolby Vision pulled ahead of HDR10 4K Blu-ray when the display featured suboptimal peak brightness/ colour volume/ tone-mapping, but the gap was closed to negligible levels by a high-end HDR TV with 1000+ nit peak luminance and accurate tone-mapping.
