I made a comparison of YouTube's 4K VP9 HDR and 8K AV1 HDR encode quality: https://andrewkeyanzhe.github.io/posts/youtube_4k_vp9_hdr_vs_8k_av1_hdr_encode_quality/

The 8K AV1 HDR encode has a higher bitrate and looks better than 4K VP9 HDR most of the time, but surprisingly in some cases it shows worse macroblocking artefacts.

Hi, I have created HDR Color Meter, a color picker app that can read the both the SDR and HDR RGB values for the pixel under your cursor, as well as the luminance (nits) value.

This app is the Windows equivalent of macOS's Digital Color Meter, but with improved HDR support.
