About Strato V, Dolby Vision, and FEL

FenceMan said:
I'm more than halfway through John Wick 2 watching DV with zero issues, it's perfect.

So is some content just buggered?

Not really fair that we have to just try movies to see if DV works, shouldn't this stuff be tested?

Seems like it, so far I have only seen 2 very brief audio drop outs, both in DV in Empire Strikes Back and Revenge of the Sith (haven’t checked the HDR10 version for this).

reproducible? or sporadic?
 
Here is an example from Star Wars the Force Awakens. First photo is the DV version. 2nd is the HDR10 version. Notice the big red banner. On the DV it's more orange, while on HDR10 its a deeper red. I also have this on UHD disk and it's red like the HDR10 version. Seems that some DV titles have colors that are more washed out.

Going to Agree. Top pic is DV, bottom is HDR10. You can see the reds are more saturated in the HDR10 picture. Peppers skin tone is a lot more natural in HDR10. DV for some reason looks cooler/more washed out. You can also see the difference in the green of the trees behind. So far it seems isolated to Disney movies?
 
Did you calibrate your TV separately for Dolby Vision and HDR10? Am I right in thinking that the TV is decoding the ICTCP color space in TV-led DV, whereas the Strato V is decoding ICTCP for HDR10 output?

I'm thinking the DV version is using the wrong gamma. It appears to be too low. Perhaps closer to 2.1 or 2.0. That may be the reason why the color looks washed out and contrast not as deep.

If only the people that encoded it would tell us what the issues are....
 
These are all the same things I'm seeing. DV on DIsney plus etc. looks fine. DV on the Strato V is much more washed out. I don't bother downloading the DV copy anymore because at best it's going to be the same as HDR10 and much of the time the content I watch only looks worse.

I notice duller/washed out when playing DV titles on non DV projector...something is definilty wrong with the V and some DV titles regardless of display type. I also only download HDR10 versions...really wish we could make that the default since it makes no sense to download DV version in my case!
 
I'm sure they will figure it out. DV on projectors (what I have) is still in the gimmicky phase at this point anyway. HDR 10 looks fantastic.

Yeah. What is baffling to me is that the Strato V knows its hooked to to a non DV display yet defaults to downloading DV versions.

I would guess there is a domino effect going on. I doubt they anticipated the DV movies looking worse and thus defaulting to DV made sense. Now that they know this my guess is we will either see a DV improvement or the ability to default to something else on a future upgrade. Right now, worst case, it's 10 seconds if I'm slow to change the download setting.

Unfortunately, dolby vision profiles are provided by Dolby Labs. It will be up to Dolby to address the issues, and they are known to be quite slow to fix issues. This is likely not a K device problem. DV has been a problem on TV's for years, specifically with Sony, and it took Dolby over a year to fix DV on the Sony A95L.

Hm, how could it be a content issue if there is an issue with a specific display?

Dolby works with each manufacturer. The DV profile provided to K for the V could be the problem. Since multiple displays look washed out, the one common factor is the V, and DV.

Yeah, but the DV profiles are still standard to my understanding. So if it looks washed out on some display and some not, how can it be a content issue?
I haven´t dealt much with DV in the past since we almost exclusively do projector setup. But whenever I come across a "washed out" image, that has most likely something to do with colorspaces not fitting between content/player/display.
If you output a larger gamut to a display with a smaller gamut setting (e.g. outputting bt.2020 to a bt.709 display), then you get oversaturated colors ("sunburn"). If you do it vice versa - outputting a smaller gamut to a display set to a larger gamut - then you get washed out/faint colors.

Could it be that there´s something wrong with the gamut alignment between Strato V and display?
