And green seems to be FR with a 20 ohm amp(amp+possible resistor+cable usually count as amp). See green as a somewhat extreme version of the EQ you could feel when moving to a cable or DAP of higher impedance.
If the cable counts as part of the amp section, and different cables have different resistance - which affects how easy an iem is to drive, wouldn't it follow that cables affect the end product; sound? Though it's been stated by many they don't.
I was amazed to read how alcohol affects the inner ear, staying there for several days longer than the rest of the body, it gave me incentive to drastically reduce my intake as over lockdown I was drinking way too much and it was impacting on my listening experience.

If one IEM cable is 20 ohm more than the other and it's not on purpose, kill it with fire!
For the rest, anything impacts anything else, what should probably be relevant is the magnitude of impact. On those extreme cases like the andro, you’ll get like a dB of variation from maybe half an ohm increase at the ”amp”, assuming a very low impedance amp+cable from the start. Obviouly this isn't nothing and audibility can rapidly become real even between some cables, as IEM cables can easily have half an ohm or even 1ohm between one another.
But I can take most of my IEMs and get nothing audible even with several ohm increase beside overal gain change at some point. Some IEMs show basically the same FR with 50 extra ohm as ”amp”.
The usual rule of thumb is to follow impedance bridging. Have amps near zero ohm and drivers not near zero. The at least 1/8 ratio is often brought up. If your IEM goes as low as 4 ohm, then the total source impedance should be 0.5ohm or less. With that logic you shouldn’t find yourself in a situation where one cable has 0.5 ohm or more than the previous cable as the total source impedance should never reach 0.5ohm when using those IEMs.
Here we're discussing IEM that basically won't allow the user to have at least the 1/8 ratio for impedance. It’s not too far fetched to blame those IEMs for being out of spec instead of using them to prove that cables matter.

Line level signal cables do not matter, because the impedance levels are so high the impedance of the cable itself is insignificant (e.g RCA output impedance = 120 Ω, RCA cable impedance = 0.8 Ω and input impedance 47 kΩ and everything is very resistive).
Speaker and headphone cables CAN matter, if/because the impedance levels are low AND the load is not usually very resistive or constant at all frequencies. That's why you have electrical requirements for the cable, but it doesn't take expensive snake oil cables to fulfil those requirements.
wrong. the cable needs to be made of silver that has never been exposed to oxygen and assembled in outer space. and it must cost at the very least $20,000.
All my cables are made of 99.99% pure unobtanium. I'm saving up for cables that are 99.9999%. I hear that is night and day and even my wife can hear the difference!

but they HAVE to be assembled in outer space or on the moon for best sound quality.
I hear a night and day difference with moon-assembled cables compared to earth-assembled. The music is more vibrant, nuanced, lifelike, nuanced...with increased resolution, dynamics and sound-stage.
I have also found that the sound from my speakers is better if they are sitting on stands made from unobtanium. Night and day difference.
