My somewhat confused perception is that due to environmental restrictions all new car paint is a basecoat/clearcoat or basecoat/tintcoat/clearcoat. Clearcoats have been used for quite some time on colors - black and white have been the holdouts. The real answer is going to have to come from the dealer/Lexus but I suspect that you are going to find that it is a clearcoat.
If you you feel the need to get the answer yourself, try some polishing compound on a clean white rag on an inconspicuous area of the car. After a few passes, the rag will have picked up at least some of whatever the top coat is - black=paint / clean=clear.
