Since you do not appear to have any links to images I will take your word on it.
Keep in mind that low density sensors do not benefit with "better" lenses beyond a certain point. That point being much lower than higher density sensors. The advantage there is not needing to buy the highest resolving lenses available thereby saving some cash. Not a bad thing, imo.
As far as older tech..... they are only older in their ability to render finer detail and are noisier at higher ISO. All the firmware stuff I really couldn't care less, much like you.
