-Using Youtube or Netflix
-HDR (with any local dimming setting)
-SDR with local dimming on "HIGH"
When using Youtube and watching first a HDR video and then switching to a SDR video (with local dimming on "HIGH") there is a really strange bug.
Bright spots in the picture of the SDR video are basically pixelated areas ( see attached picture).
Only changing local dimming to any other setting and back to HIGH completely fixes the issue - until watching a HDR video again.
This can be 100% reproduced.
Issue also present on Netflix app.
Worth to mention:
Is also appears no matter what local dimming mode is used on HDR before. As long as SDR mode uses local dimming on "High" the issue will be there. If SDR is set to "Standard" the issue won't show up.
switch to minute 18:26 of below video after having watched HDR content before and having SDR mode using local dimming on "high"
Watch "Klassentreffen 1.0" (timestamp 1:53:20-22) after having watched HDR content before and having SDR mode using local dimming on "high" you will see pixelated/crushed area in left lower corner.
Same issue with HDR as well as major issues with local dimming in general. This needs to be changed to an adjustablebar like an adjustable backlight instead of automatic. The automatic is what I feel is causing the issue
