A couple of tests on video content generated from still images.

#1 Lenna (preview: wikipedia.org/wiki/File:Lenna_(test_image).png; download: lenna.org), 512x512 RBG24 converted to 8-bit 4:4:4.
x264vs || relative filesize 100.0%
x265vs || 104.7%

#2 M87* (preview: wikipedia.org/wiki/File:Black_hole_-_Messier_87.jpg; download: eso.org/public/archives/images/original/eso1907a.tif), 7416x4320 RGB48 converted to 3708x2160 10-bit 4:4:4. Do note that the original TIFF is a gargantuan 183 MB file.
x264vs || 100.0%
x264f || 100.8%
x265vs || 103.2%
x265f || 104.2%
