PAI aircraft textures

Any users of PAI aircraft notice a differance in texture quality between airline liveries? I've started replace my default aircraft with PAI aircraft in FS2004 using their new installer and noticed that there seems to be a differance between say Delta colors which are crisp and solid and Continental or USAir which seem to have a some bleeding and a shimmering effect to them. Don't have FS2K2 anymore and can't recall if I had the same effects there or not. John Fitzpatrick
