Unless I misunderstand what is published, the firmware for the 1 ppm
TCXO is only to allow it to be tightened up to 0.5 ppm, and does not
affect the basic 1 ppm TCXO. I have the 1 ppm TCXO and even though I
haven't done any scientific calibrations, I'd say it has a 1 ppm
capability... or pretty darn close to that.

I'm not sure anyone knows the answer to your question: Elecraft still
isn't shipping firmware to support the 1ppm TCXO...although they ARE
happily taking our money for the units. (I have one installed).

Does the higher accuracy TCXO result in lower phase noise? If so in dB
how much lower would one expect out of a delta in 4 ppm and 4.5 ppm.
This is assuming the 4ppm which one will get with out implementation of
firmware correction and 4.5 ppm delta which one will obtain once this
feature is implemented in firmware.
