On DSL Checker, it looks like my line is capable of 71 Down and 17 Up. Actual achieved is 70 Down, but 12 Up.
Down seems like achieving max possible, yet Up is at the lowest. Is there profile / other reason why Up is not also at max of 17? Is there anything I can do to improve Up speed?

I think modem is reporting Up SNR incorrectly...
There is absolutely nothing you can do and as you are within estimate BT won't do anything either.
Upstream operates at different frequencies to downstream What may be OK or one can have an effect on the other.
Thanks for your reply. Looks like down SNR has dropped to 3 dB with 17.5 attn, so probably getting the most possible down. I do see Up SNR is 6.3 with 0 attn, so could probably squeeze a little more UP if that SNR could be reduced too.

up noise margin will stay about 6db unlike the down margin at 3db as G.INP active
looks like you have as good as you will get
