I didn't see anything abnormal.
Random bits of KR at low throttle % and low loads tend to be common in my eyes for 5.3 trucks. My buddies 2011 gets tons of random blips while bouncing in and out of DoD and just crusing around town.
I'm sure if the truck was running 91+ octane, the WOT kr might drop a little bit but some fine tuning could get it closer to zero.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
That looks like real KR to me as it is happening under load. Even with the KR your still running ~26 degrees of timing which is good for an LS motor. Even the best of tunes with good gas usually dont run more than ~28 or so. Pull out the timing where its knocking plus a degree or two and i bet it runs even better.
Remember its better to run several degrees less than KR point vs. one degree too much as your fighting the cylinder pressure.
