Meaning, as Thomas more precisely and scientifically (as compared to his two thumbs rule ), points out for those of you not having ITU Ties access (e.g. https://www.itu.int/md/R12-WP6C-C/en ), ITU testing of HEVC 4K content (10 different samples/clips) indicated (by subjective assessment with real world viewers rather than analyzing with PSNR, etc.) that 4 out of the 10 clips needed 30 Mbps in order to deliver the benefit of 4K (UHD) resolution.

Worse for current 4K streaming aficionados is that even 40 Mbps wasn’t satisfactory for 2 out of the 10 clips in order to achieve a high opinion score.
