Wax or sealant just protect car paint and gives some shine by adding carnuba contents.
Paleness should be removed by cutting through a little layer of clear coat through compounding or polishing.
If it has never been detail I recommend you to go to a good detailing studio like luxe auto spa or auto extreme they will do paint correction by professional tools.
Otherwise what you can do is to:
Wash car with some shampoo like tac system mystic bubble
Clay bar with meg clay bar or 3m
Use a compound like 3d one speed by hand or polisher
Then use a polish to do finishing stage sonax polish and wax 3
Then top it with a sealant like soft 99 fusso coat.
Try not to use a carnuba wax as it will pale paint over time.
I have also done this same procedure on my civic 2013 tafetta white
