Video player's dynamic color range is off
 

The D3's video player's dynamic color range seems to be 15-235 rather than 0-255; anyone else notice this? It basically makes blacks look gray, even though the OLED screen can turn black pixels off. Here's a comparison I made between the S9 & D3 playing the S9's stock video (D3 is stock 3.33 and both are on max brightness):

Yeah, me too, on all the formats I've tried.

This might be the reason why my D3 colors look a bit washed-out compared to the J3? The J3 for me is much more vivid.

If you mean while playing videos, yes. This is only within the video app.

Yes, it limits reds/greens/blues which makes up every color. AMD and Nvidia video cards have the same setting in their drivers that sometimes gets set incorrectly.

This is extremely annoying, and a reason why I still watch videos on my J3 instead. Did anyone find a fix for that washed out contrast ratio bug in the meantime?

I'd bet they added a backlight behind this OLED display Might have been to make it show up better when outside. Never seen an OLED that didn't look great except the D3's.

It does show true blacks in other screens, though (or at least it seemed to me that way on a cursory glance) - it seems the contrast issue is only related to video playback.

Any difference with alternative video players?

I tried rockplayer and the black levels were perfect; however it was very jerky due to software decoding and the relatively slow cpu. There's definitely not a backlight. Kind of depressing that this hasn't been fixed yet :(

The contrast issue is definitely related to video hardware decoding. Players that support both, hardware- and software decoding, like Rockplayer, IMPlayer+, Soul Movie, etc look fine (but play choppy of course) in software decoding mode, but in hardware decoding mode the contrast goes bad.
