Since you have no experience as developer - there is no pay raise justified.
Once you've proven some skills, this might be the time to speak about it. And in smaller companies it's not too uncommon, that admins do programmer jobs and that programmers do admin jobs - since the field of expertise is still somehow similar and the skill sets often may overlap.
I mean, to exaggerate as an examplea little: you could write a new UHD app for them.
