Those are great fills, and any differences are as likely to be due to original fill as to actual ullage/loss.
I would go w/ Dale's thought here...minimal. More a function of btl variation than anything.
I've had btls in which 1/3'rd to 1/2 ullaged away (mostly LH Zins) thru leakage around the cork and the cork
plopped down into the btl when I attempted to extract it, sometimes. The wine was still drinkable, if a bit tired.
But not (overly) oxidized and certainly not turned to vinegar. Was it as good as an uncompromised btl??
Never had the opportunity to make that comparison.
But my feeling is if the btl is ullaged down to the bottom of the neck, or onto the shoulder...meh.
