If you want to create such a sample, take 2 short HEVC clips with
different resolutions, extract the ES, and concat them together:
ffmpeg -i INPUT1.mp4 -codec copy -bsf:v hevc_mp4toannexb OUTPUT1.265
ffmpeg -i INPUT2.mp4 -codec copy -bsf:v hevc_mp4toannexb OUTPUT2.265
cat OUTPUT1.265 OUTPUT2.265 > mixed_res.265
