ACME 300B matched pair - different blue glow intensity - new in amp world

Hi, I bought new pair matched ACME 300B. 

Everything is perfect, but between tubes there is small difference in blue glow intensity (photo in attachment). Amp socket swap, doesn't change that. One is brighter that second one.

I know the basics (from where is this effect and why), but I don't have a practice..

Due tubes where quite expensive, I just wanna be sure that everything its fine, or this difference in blue glow intensity, mean something that I should worry about ?

Thanks for help

So, I believe what the photos show is that one tube has the blue glow and one doesn’t and the tube that glows switches sockets… showing it is a characteristic of the tube and not the amp.

yes, exacly. I swapped them to check that is not socket issue.

I will ask the dealer. Thank you.

If anybody would like to add a penny, you are welcome
