IMO, there simply is no valid explanation for LE to not have investigated the two unknown male blood DNA samples B and D to the fullest including doing IGG. If these samples were touch/transfer DNA, I would be less concerned about them, but they are blood DNA in a situation where the killer or killers are likely to have gotten cut because at least 2 of the victims, KG and MM, are known to have fought for their lives. JMO.
Possible outcomes from unknown male blood DNA sample B mixed with female DNA and I'm going to put a asterisk (*) by every scenario that might tell the investigator more about the crime:
killer and victim*
killer and unknown female*
killer and known female*
unknown male and victim*
unknown male and unknown female*
unknown male and known female*
known male and known female
known male and victim*
known male and unknown female*
Not enough DNA to evaluate/spoiled sample/degraded sample
JMO.
So, out of 10 possible outcomes, 8 outcomes would have likely told the investigators more about this crime, whereas only 2 outcomes would not. JMO.
Unfortunately, we still don't have clarity about exactly where Unknown Male Sample B was located. There are two bannisters for this particular staircase as seen here in photos 1 and 2 of the living room:

There is the horizontal bannister that leads from the area of XK's bedroom to the living room and the angled bannister that leads down the stairs from the living room to the 1st floor. CSI was seen to take a lot of time in the area of the horizontal bannister that leads from the area of XK's bedroom and do quite a bit of swabbing there. But we still don't know the exact location of the blood mixture. JMO.
Possible outcome from the bloody gloves that CSI found outside of 1122 on Nov. 20 and again, I'm placing asterisks on the outcomes that could further knowledge of what happened for investigators:
Killer*
Unknown Male*
Known Male*
If the DNA on the gloves directly matched the DNA on the sheath, then we know it was likely deposited by the killer. The gloves should be examined for cuts/tears. This could be the actual explanation for how the killer's DNA got on the sheath and from that aspect alone, the bloody gloves are very important. This needs to be answered. JMO.
If the DNA on the gloves did not match a known male visitor to the house, then we know there may have been a second killer. JMO.
If the DNA on the gloves matched a known male visitor, then this would lead to follow up questions about 1. why they had on gloves and were bleeding inside them and 2. why the gloves were outside the house in the aftermath of the murders. Questions could have been asked to exclude Unknown Male DNA D. JMO.
So all of the possible outcomes for Unknown Male DNA D would have added to the knowledge base about the crime. JMO.
You could make a supposition that some party guest cut himself at one time or another, and that would be a good screening question for the investigators to ask DM and BF - "Do you know of a time where one of your male guests cut himself and bled inside the house?" and if the answer is yes, then "Do you know what he did about it?" the answer might be "He went in BF's bathroom to get a bandaid," which might explain the blood on the bannister, however, we don't have any evidence that this question was ever asked of DM or BF. The house was completely remodeled in 2019 and changed from a 1 story house with no stairways to a 3 story house, so it is possible that LE could ask this question of everyone who ever lived in that house since the remodel and even the property manager and/or workmen who have been in that house since the remodel. There is not likely to have been more than 2 dozen residents and a handful of workers since 2019 so it is not too onerous of a job to simply call and ask these questions. But there is no evidence that even this simple investigative task was done. To me, an absence of information is just an absence of information and a sign of a lack of detailed investigation. JMOO.
Now, going back to the sheath, RN says this is the part of the sheath that was swabbed:

So this indicates that the DNA from the sheath may have been from the bottom side of the snap, which is not powder coated. In fact, it is untreated brass which is known to degrade DNA on contact.
Limited success in DNA recovery and STR profiling from brass substrates, such as ammunition, has been ascribed to oxidative damage and/or inhibition caused by c

RN also made it clear that the leather portion of the strap was also swabbed in its entirety. There, so far, does not appear to have been an explanation as to exactly where the male DNA was on the snap or leather portion of the strap or if they were swabbed separately. I hope there is further definition of this which will come to light during the trial. It is important for furthering our understanding of the meaning of the touch/transfer DNA in this case. JMO.
All JMO.
