I don't find the hours posted in my manual, and I searched it electronically (PDF). All I found was:
Use to automatically adjust the picture brightness to give optimum contrast performance.
Adjust the brightness mode settings.
Bright: Choose "Bright" to increase the brightness.
Eco: Choose "Eco" to dim the projector lamp which will lower power consumption and extend the lamp life."
However, I did see where it says that Dynamic is ~30 - 100% brightness. So maybe the amount of time it spends at the lower end of the range explains the difference. I just know that when I enable Dynamic Black, I hear the fan speed up and I, perhaps mistakenly, assumed this meant shorter lamp life.
I'll have to play with it again when I get home. I used Dynamic Black initially and liked it for the most part, but I noticed some other issues like posterization that caused me to turn it off. I've since made a lot of other changes and will concede that what I was seeing may not have actually been due to Dynamic Black after all. I'll try it again and let you know.
Thanks for pointing this out.
BTW, I also have mine in a completely dark room with a 106" Silver ticket screen, a Denon S730, and an Xbox One X. I'll be happy to post up some screen shots of my settings for you. I've tried to find the best compromise between HDR and non-HDR material, as I (read "my wife") doesn't want to change settings every time we switch between the two. The results is that HDR is perhaps not as vivid as you might expect, but it looks more realistic to me that way anyway. Some HDR looks oversaturated to me, especially skin tones.
