The primary exception I can think if is that UHD Blu-ray's peak bitrate is a lot higher than 40 Mbps, so that probably should be done at High Tier and then --vbv-bufsize and --vbv-maxrate specified per the BD spec.

Yes, the uhd blu-ray standard specify high tier, the lower max bitrate is set as other disk based media cause of the limitation of the read bandwidth from the disk. The decoder itself in those units can probably handle the full data rate of high teir.

I wouldn't assume that, 4.0 high specify a higher data rate then 4.1 main.
