Profile only means that a DNA profile of some kind exists. If it was a Complete Profile, it would have been described using the words Complete Profile. But it wasn't. So, basically, without seeing the discovery stating it was a Complete Profile or BT actually stating this was a Complete DNA Profile or some expert for the prosecution describing it as a Complete DNA Profile, we don't know if it is or isn't complete at this time. And frankly, the defense expert Bika Barlow stated its was a partial profile (see below.) However, we do know that the sample was touch DNA."Profile" is a term that means a complete profile.
When it is not complete (see below) it is called a "Partial Profile"
Partial Profiles: In cases where samples have very low quantities of DNA, are exposed to extreme environmental conditions or are not properly preserved, it may be difficult to obtain a full DNA profile and the test may only yield a partial profile.
"They are also analyzing trace amounts of DNA, including the “touch DNA” left behind when someone touches an object. These types of evidence can be far more difficult to interpret reliably than the relatively simple DNA evidence typical of earlier decades. "
"With DNA mixtures and trace (touch) DNA, the results can be ambiguous and difficult to understand, sometimes even for the experts."

DNA Mixtures: A Forensic Science Explainer
What are DNA mixtures? And why are they sometimes so difficult to interpret?
We need to avoid getting ahead of ourselves. We don't really know if the touch DNA yielded a complete or partial profile. All we know is there is some kind of profile. We don't know much about it at all except that it was found on the brass snap of the knife sheath and was skin cells - touch DNA.
In addition to this being touch DNA, apparently other DNA samples were taken:
Bicka Barlow declaration

"From the discovery in this case, it appears that at least three, and possibly four profiles were uploaded to the CODIS database prior to Mr. Kohberger being charged."
Then on page 13 it says:

The last sentence above indicates that Bika Barlow is saying the BK profile is both "ambiguous and partial". Is she right? IDK. But I find Bika Barlow's comments interesting in light of the fact that AT now wants the courts permission for the defense investigator to be involved in the DNA.
