It mainly depends on the amount of details and how they are preserved at different quantizers.
Assuming crf scaled linear with file size is wrong. If there are no details, a lower quantizer will retain, lowering the quantizer / crf does not change the output.
(Sometimes quantizer x-y can give the same output, but x-(0.1) or y+(0.1) can be a lot different.)
I tested:
a. an SD clip and got:
b. HD clip and got:
c. 4k clip and got:
With software encoders, you usually get way more diversity in sizes and detail retention, since they usually take more/better psycho visual effects into account.
