Hi there and
to the forums!
Sprite sounds like a sweetheart, even if he is a bit flighty at times
How long have you had him?
I reckon he just needs more time. From what you're describing, he's definitely on his way to becoming more comfortable around you, but isn't quite ready for that.
There is really no set "time" when a bird becomes tame, some birds take longer than others to be fully comfortable with humans.
Simply sitting by his cage and reading out loud (or singing softly, if you're feeling adventurous
) can really help to build that bond of trust. Offering him seed from the palm of your hand and sitting like that can also be very beneficial.
Also, just letting him do things as he'd please--i.e, don't make him come out if he doesn't want to, and if he does, let him go back on his own time--this will make him less stressed in the long run.
I think you're doing great at letting him take things slow if he'd like, so keep on that route and as time goes on, he likely will enjoy spending more consistent time with you
