I've seen a slight haze on the inside of the cellophane with some cigars I've bought. I figured they were overly humidified when I put em in there. Also, i have a pretty cold storage area, rarely over 60F. I do have a box that all the cello was hazy whitish and it never went away. The cigars were/are very oily, and I think it was just the oils discoloring the cello.
I'd recommend ditching the gel media, and just stick with bovedas though. But having the boveda in there with the gel is better than the gel alone.
I'd not worry too much about it unless it's a recurring or persistent issue. Might want to remove the cello, or cut off the folded end of the cello to expose the foot and allow more air exchange.
