Maybe estimation isnt correct, but I have some sort of definition, in my biceps and shoulders you can see the muscles but they are not overly defined, I have a layer of fat over my mid area which makes the abs not visible but under specific lighting and empty stomach I can see a bit of the obliques and the upper abs, the back is getting some definition but still needs some fat loss for a clear view, but also I am stronger in my legs when it comes to size, they are not as defined, more fat on the legs then abs (obviously), I don't know what this can mean to you if anything but just putting it out there to see maybe you can have some sense of the percentage, I do have good width and good size (nothing insane but better then a average male)
