^ thanks, sir!
I may be naïve yet. I don't truly understand how to interpret a washed out color. so far with all my 4K HDR BT2020 movie downloads, I'm all wowed by them. colors are great, clear and detailed. picturesque scenes are more appreciated in 4K HDR rather in 1080p whether 8bit or HEVC 10bit.
my Shield setting is the recommended one: 3840x2160 59.940 YUV4.2.0 10Bit BT2020. it is set and forget. I do not change regardless of what resolution and color space of the material I watch.
I hope to see a washed out color to know how it looks like and understand/learn something more.
maybe other owners could share their observations as well? tia!
