On my 2021 V7, I am seeing the AirBox blow by cap filling up with oil as seen below. Is this of any concern?

Yes, it means your oil level is overfilled, and it's pumping oil into the air box, which problems it causes are well covered here. Be sure to do a search and spend some time reading.
 
Thanks Todd, but I promise you I did search this site + the internet regarding this before posting a new thread. I am not experiencing what some of results indicate.

1. There is no evidence of overfill of oil. I ran the bike five minutes and double checked the oil levels. it's between max and min line.
2. There is no oil/residue/sludge in the air box. I removed the filter and put a rag inside of the air box. Dry as bone. Oil/Liquid is only seen in these transparent caps. There is no mention of these caps in other threads. There is no mention of these caps in the service manual.

Edit: There is no mention of these caps in other threads
I stand corrected. Found a thread regarding the cap. My first point still stands though. My guess the original oil from factory was overfilled.

Pull them off, drain and clean so they don't stain and go ride. FWIW the V85 can be horribly overfilled and not dump any in there and I would think the V7-850 would be the same.

I just drained both caps (there's one hidden behind the left hand side panel). It wasn't much liquid. My guess this is some oil mixed with rain water. The airbox and filter are completely dry so I am comfortable riding.
 
Also note that the specified oil refill quantity for the 2021 V7's, including a new dry filter, is 1750cc, less than the 2000cc specified for earlier V7's.

Noted, thanks for sharing that.
