My rolling furling jib has developed a 3ft long chord-wise wrinkle above the foot. Has anyone developed a heat/pressure technique to bring the area above the glass transition point (Tg) and removed a wrinkle?
Ironing out wrinkles in sail laminate possible?

That jib is most likely not the optimal shape for furling. It will happen again and again. Give Dave Alexander a call. He's the VX sail designer of choice.
do you think that wrinkle comes from furling it in an overlapped condition and leaving it that way?
if so, you could try moving the jib lead back when furling to change the ratio of tensions on the foot & leech.
zeros on furlers sometimes have a similar problem of furling up unevenly, solved it by using twings to change the angle of attack
if that does not work, furl up a little bit & pull down on the foot
furl up a little bit & pull down on the foot
furl up a little bit & pull down on the foot
repeat until it's furled w/o the wrinkle.

Maybe it's the lighting, the gold colored section looks delaminated to me

Correct. Yes it was overlooked at some point and furled with the wrinkle. A little finagling during roll up can avoid the wrinkles. I have multiple jibs which are less wrinkle prone. The one pictured has developed this wrinkle which has set in and is now the normal condition.
