We're looking at two Bosch dishwashers - one claims a noise level of 50 db,

Bosch has other, more expensive dishwashers in the mid-40 db range - they
are beyond my price point, but with a noise level that goes that low, maybe
the difference from 53 db to 50 db will be enough to justify the extra $100.

Is there an perceptable noise difference that I'll notice when the 50 db
machine is running versus the 53db machine?

a 100W stereo is 3 db louder than a 50W stereo

However, 10db is perceived as twice as loud.

Do you have a stereo with a volume control marked out in db?
Play some thing at medium-low volume. Move down three db.
3db isn't worth $100 in my opinion, but if you have such a stereo then
you can make your own decision.
