Probably, but that factorization is arbitrary.
I don't even think it's correct.
That number is not divisible by 512 (block size)

My Poke3 backup is 31,268,536,320
That's divisible by 4,194,304 or 2^22, so certainly by 512
2^35 or 32GB minus 31,268,536,320 divided by 512 is 6,037,504
So that's how many pages get used for spares.
Let's call it 9%
But that would be presuming that they gave you 2^35 to begin with.

Yes, you can extract the system.img out of super, but you have to remake super to put it back in. You can't just flash it by itself.
