Yes, looking at the models page suggests that.. Looking at the linked slideshow there, it also seems that for proper analysis, you have to upscale to 4K.

EDIT: with video upscaled to 4K, it runs out of memory quite often. Even with core.max_cache_size = 1024, the usage jumps to over 8GB quite fast and then the errors appear. I have 16GB on the machine so it's really not using all the memory.

Code:
Start calculating VMAF score...
Script exceeded memory limit. Consider raising cache size.
error: aligned_malloc failed for data_buf.
error: aligned_malloc failed for data_buf.
error: aligned_malloc failed for data_buf.
Exec FPS: 3.574859
VMAF score (harmonic_mean) = nan
