Maybe they just didn't put the makeup on because all we see is the back of his head in those particular shots.
Over Analyzing Alert!
Its programed to go off before you do.
The DS is eating him away. In AOTC he looks thiner faced, older & paler than he did in TPM. Assuming that there's what 10yrs between TPM & AOTC, & then a few more yrs to ROTS & from there 20yrs to ESB (the 1st time we see him in the OT) don't you all think he would be looking like he does in ROTJ?. I don't think anybody does that to him not Vader or Yoda, i think its what happens when you become all consumed by the Darkside of the Force. More of a moral point from our old friend GL - Evil destroys you!!.
