I was able to change channels on my docsis 1 modem. Its just the usual channel hopping process, turn modem off for long enough then turn it back on again and hope it uses a new channel, so my experience was not that it always used a primary channel.

There is no doubt tho that the docsis3 experience on a docsis1 modem is severely hindered, qas probably remembers when I signed up to 30mbit on the docsis1 modem on the 20mbit service on docsis3 network my speeds were at the time chaotic, I upgraded and got the superhub and then on a docsis3 device they stabilised and that was with a 50% higher speed package also.
