You need call your local Genesis dealership and they'll be happy to tell you. Then call Safelite and ask what they charge for an OEM Windshield replacement. You're not going to get an OEM quoted by safelite on the internet website.
You've commented with regards to an aftermarket windshield on both occasions, not an OEM windshield from Safelite. If you didn't ask specifically for a BMW or Chevrolet OEM windshield, you got an unbranded, aftermarket unit which vary vastly in cost. OEM windshields cost considerably more, because they meet the manufacturer's specifications and branding. Safelite won't put one on by default.
Then the projectors, sensors and both cameras have to be realigned by the dealership. Safelite is not capable or equipped to deal with them and their finite adjustments. So combined cost for the new windshield, is $3.5K to replace.
I know, I had to have one replaced, it was an OEM windshield, not a default aftermarket from Safelite. Replaced by safelite and calibrated correctly by the local Genesis dealership.
Just because you've never owned a Genesis G80 Ultimate or had to replace a windshield on one, most certainly doesn't mean you're aware of what a new OEM windshield costs. You don't, obviously! We're talking about full replacement, not just the windshield cost. You're not going to purchase a windshield, then not have replace it. I dare say none of us have the equipment or technical savvy to replace it, mate!
You also didn't take in account; the initial cost for the OEM windshield or the cost compared in 2018 to now (higher cost and less availability in 2018). The only windshield available at the time, was a
Hyundai OEM windshield. There were no aftermarkets available.
Frankly, there are so many variables you didn't consider including; the shape and size of the windshield, the Genesis G80 has a larger windshield then both the BMW and the Camaro. It's was an imported OEM windshield from Korea, not the US which adds, more cost. Do I need to go further?
This is very similar to; jumping into a demo 2019/20 Hyundai Kona once, for the space of a half hour. Not taking the time to properly adjust the HUD thru the user menu setting for yourself personally. Then claiming it's not a true HUD (which it is) or a poor setup, without doing your own personal diligence. Frankly, it's an uninformed appraisal, full of misnomers and poorly derived comments. I say this with all respect, being a present and past owner/operator, who utilizes/ed one daily.

Oh and on top of all this, even after the dirt road! It's still not cost effective for the op of the thread, to retrofit a HUD system, from a Veloster to a Veloster N.
Nuff said! 
. Not necessary, then I'd have to dig out the original bill and post it!
