Netflix had Dolby Vision and HDR, this is just adding HDR10+. HDR10+ is similar to Dolby Vision in that it give your TV dynamic metadata for the HDR. Constantly adjusting min/max brightness of the scene.
For dynamic metadata Dolby Vision support is much more common in TVs, some brands like LG don’t have any support for HDR10+ even in their high end TVs.
I am pretty sure from a content perspective Dolby Vision is also much more prevalent. It does look like most streamers support HDR10+, but I don’t think much of their content is available in HDR10+.
Anyways still a good change. HDR10+ is royalty free unlike Dolby Vision, and it is backwards compatible with regular HDR TVs.
Often in dry pipe setups there is still a stopper in all of the sprinkler heads that has to melt to let the water out. This is common in places like datacenters or other places where accidentally hitting the sprinkler head would cause major damage from the water.
Basically smoke/heat detectors trigger the pipe to fill, then heat from the fire releases sprinklers wherever it is hot enough to melt the stopper.
But I suppose there are cases where the fire might be expected to spread so fast that they don’t put the stoppers in and just let all of them go.
