I also noticed in your post that High 4:2:2 Intra Profile is not flagged, looking at the sdk documentation (I did not look at the source code), I cannot find the intra profiles either. It is ofc possible to do intra-only encoding, but the profile flag should be correct as well.

There're spikes in nvenc encoded streams still, the filler will not eliminate those?

According to the nvenc documentation maxrate should eliminate those, but maybe thats only in effect in vbr mode, but maybe vbr+maxrate creates more of a "true" cbr bitrate distrubution?
