Mazda dealership ceramic coating sounds genuine. Is it though?

I asked them what their process is and this was their response.

Gloss Enhancement polish with machine Pressure Washing Full vehicle details interior and Exterior
Clay bar Decontamination 3 layers process 10H Graphene coat Cured with Specialised dome infrared lamp Give the best result in terms of gloss level, durability, hydrophobic and smoothness effect No annual inspection Lifetime warranty

Graphene Interior Protection ( head unit screen ,dashboard, doors trims , Carpet floor, Leather seats, steering Wheel)

Blacktown Mazda, Sydney

Does the process sound about right? I want to go with them for the lifetime warranty but only if they actually do the coating right.

If I decide to go with them, how can i confirm if they actually did a good job?
