No don't worry so much about the Ip value , as long as it is the same on all four. Some places will put a sticker on the base of the tube. Apex tube matching puts a label on the base of the tube with the value as measured on their equipment.
I have had pretty good luck with the JJ tubes I have had that were Apex matched. There are other places that fully test and grade their tubes in a similar way
On your amps if they have an LED for bias will be around 50mA when it starts to glow brightly. I use this when I retube a 6L6 or EL34 based amp.

It is a great tool for adjusting bias and safe because you are not using meter probes on test pads
Quicksilver has all of the bias values except the Mid Mono so I asked Mike and he said 53 mA for best performance. That VHT tool is more accurate than the LED , although it gets you close if set to where it just starts to get bright.
