Also, which HDMI port did you use (if it matters) for the ATV on the B6P? Thanks.
Attaching my ATV did not change settings on the TV. That should not happen!!
When ATV starts up the first time, it does detect an HDR TV and sets itself up to output HDR (or Dolby Vision). Before I matched the OLED light, contrast, brightness and color settings between HDR and SDR, video from ATV was overly bright. Once I matched the TV's HDR settings to those I set for SDR everything settled in.
I never saw odd blotches or overly saturated colors. I can't explain that one unless the TV's settings being used are off.
I should mention I have a Pioneer SC-LX701 AVR in the loop. Until it receives it's Dolby Vision update, I'm limited to HDR10 from ATV and my Oppo UBP-203.
My TV settings are OLED light 100, Contrast 64, Brightness and Color 50. Only the contrast is different from factory defaults.
I have ATV set for HDR 4K YCrCb 4:2:0 12-bit if I recall correctly. I choose 4:2:0 over 4:2:2 because something in my chain was dropping back to 8-bit video with 4:2:2.
My AVR is connected to HDMI 2 on the TV.
