I recommend you send me $500. What reason would I have to lie?

Slip a short piece of tubing over the bleeder valve, so it doesn't drip all over everything, then crack the valve open to drain into a container. It'll slowly drain, but you need to make sure the reservoir doesn't run dry. Let it run until it's clear. Start at RR, then LR, RF, and LF. It takes about an hour, so find something else to do that allows you to keep an eye on the process.
BTW, I found this on the aa1car.com site for what it's worth.
"A General Motors spokesman said Delco Supreme 11 DOT 3 brake fluid contains additives than many other brake fluids do not, so it is essentially a lifetime fluid. Starting in 1993, GM began using a new type of rubber brake hose with an EPM lining and outer jacketing that reduces moisture penetration by 50%. So GM does not consider fluid contamination to be a significant problem."

The next question, harder to answer, is "in the conditions that a Corvette may be driven even on the street, can we still consider it a lifetime fluid? Or should we do an occasional flush anyway?"

My 2007 C6 has 28k miles.
Dealer recommends a brake fluid flush, power steering fluid flush, decarb service, rear differential service and transmission fluid flush.
The differential fluid was changed early on to correct noise coming from the differential.
Are these services necessary based on my low mileage?

As far as that decarb business goes..... Bring it to me and I will be happy to do that for you for free. You can even ride along. (Be careful, some Chevy mechanics destroyed a clutch on a customer's camaro taking it for a "test drive" then we're going to charge the customer for it!)
Decarb service.... What a joke.
Read your manual, try a different garage, don't let the car out of your sight.
