noticed this for SDR/HDR.....
SDR:
LD Low = Lowest brightness / Little to no LD (more like lowest dynamic range, less bright picture (for APL) and highlights, also doesn't allow the backlight to turn off completely, so no deep blacks = low dynamic range)
LD Std = Medium Brightness / Very good LD (My personal choice) (more like higher brightness for APL and highlights and allows the backlight to turn off for deeper blacks = medium DR)
LD High = Highest Brightness / Best LD but picture is a bit too bright for SDR content (more like highest brightness for APL and highlights but can cause blooming for credit rolls and turns off backlight = high DR)
HDR:
LD Low = Lowest Brightness / Little to no LD (more like max brightness is limited and blacks are raised compared to High but has a little more accurate shadow detail and backlight doesn't turn off for deep blacks. So Low really means low dynamic range and LD aggressiveness.)
LD Std = Highest Brightness / Very good LD + Samsung Tone Mapping (My personal choice) (more like has very raised APL and highlights, brightest mode but has waaay too much shadow detail shown so has the least deep blacks and allows backlight to turn off. So dark scenes will not have any deep dark look to them or balance but brighter scenes will be very bright. So Standard means standard dynamic range and LD aggressiveness).
LD High = Medium Brightness / Best LD + No Samsung Tone Mapping / Most accurate picture of all (more like more accurate for max brightness but less so for shadow detail, has crushed blacks for the same blooming control as other LD modes with brighter highlights and allows backlight to turn off. So High means highest dynamic range and LD aggressiveness).
No HDR modes are that accurate as they normally require my HDR settings adjustments even if using the most accurate LD High, it's still too bright for blacks and mid-tones. After my settings it's alot better but still over-brightening some mid-tones. This gives you the highest dynamic range possible with pretty accurate shadow detail!!!....since there is more consistent separation between dark and mid bright elements and also mid bright elements and super bright elements!
If I want a brighter more wow image I use Contrast Enhancer! 😀 But only for HDR, in SDR it seems not as good, like a crappy dynamic contrast setting. Did they change it in the last update for SDR? It seems like Low raises the highlights like normally but now also crushes shadow detail and even more so on High, why does it need to crush SD? shouldn't it just raise the highlights to give even more DR without losing detail in the darker parts of the picture? I know this may increase DR even further by doing this but I don't think it should at the expense of SD, I want all the detail and brightness I can get without noticeable blooming. Now i'll have to try CE in HDR again and see if they changed it too....I hope not, I liked the way it worked. Or maybe I didn't notice this is the way it worked before...... 🤷♂️ 😄
