I think most jellies will eventually turn yellow. However, the only jelly that I have is DW 5025d, and I don't think it will. It has a glossy finish on the jelly that seems like it will prevent yellowing, but only time will tell.
They all yellow over time with wear. If stored away, they can remain clear for 10 or more years depending on how they are stored. the darker the color of jelly, the less the yellowing shows. for example, a dark blue jelly will not show any yellowing over time. Gray will show a little bit. Clear jelly will show the most. Yellowing can be reversed a little bit with sea glow (I made a thread about this, see the tutorials section).
Yellowing is due to oxidation. Keeping the band away from light and moisture will keep it looking newer longer. Wearing it daily will accelerate the yellowing process. Wearing it as part of a rotation of watches, it can look new for years.
