My guess is, no.
God is perfect. The saints and angels in Heaven are perfect (within their nature). They CANNOT sin.
You and I, in this life, even if we don’t sin, still could. This is a result of original sin.
Does this mean that our Blessed Lady, born without original sin, was ‘perfect’? Maybe so.
Of course, Adam and Eve were born without original sin. And they weren’t perfect.
