“is there no other explanation as to why the pixels look suspicious?”
One possibility is that the document is completely legitimate, but pixels were messed with slightly just to stir up a controversy. After letting the controversy stew for a certain period of time, Obama’s handlers later trot out the original copy just to make the doubters all look like fools.
That 0dumbo would deliberately do this is in keeping with the POS’ character.
That he refused to release even when it could have saved a find flught surgeon’s career is one of the most disgusting things he has done
One thing I can easily glean from your post is that Obama has everyone guessing and nobody trusts him, (Except for his personal guardians in the media and his bootlicking radical lefties). This doesn't bode well for 'The One'. He may well turn out to be a fantastic poker player, with lots of help from the media, but very few people trust this man.

What would be the point? If he released the real BC three years ago the entire matter would be moot today, and his ratings would be much higher.
