You could try ensuring the end posts are very well attached, buy an acro prop and stick it in the middle. Add a turn more height to it every week until it's straight, hopefully giving the wood time to adjust to its new straight shape.
Then swap it out for a permanent post. Or abandon the idea if it doesn't want to straighten.

A pole support, located in the space between the door and the window, might be all that is needed. You might even be able to relocate the existing pole on the corner, by the door, to that new position.
Honestly I'd just pull the thing down and start again. There are probably off-the-shelf kits available.

Could you take a photo, looking up, from the ground, and post it? Just so we get an idea of the construction..
It's all just white plastic, similar to the fascia., nothing to see without removing it I guess, and knowing my skill level, probably breaking it!
I think it might be worth trying to raise it again as a temporary fix, but otherwise it's looking like it'll be better just to replace it. We've been thinking about a porch, so might be a good time to do both.
Appreciate it's a hard to answer, but any thoughts on a very rough ballpark cost for replacing it? Based in the south east.
Assuming a c16 timber 195 x 38 with the roof dead load of 25kg/m2 the deflection (ignoring snow loading) deflection should still be in an acceptable 14mm, my assumption is the support timber is of poor quality
Possibly a silver lining in the cloud, a good excuse to improve things.
I've had two houses that have seen their fair share of "improvements" over the years by previous owners. Half my work is in getting rid of their stuff before doing things right.
People skimp, and think they'll get away with it. In your house's case they did, as it only buckled after someone else had bought it.
If you don't like the poles you could always get a joiner to make some suitably sized gallows brackets and fit them either side of your front door and at the end pillar to the right of the window. Obviously that would not cure the bend but you could ask his advice at the same time.
I doubt there is room for 195mm in there considering insulation, deck and furrings etc. More like 145mm.
In that case 30mm sag with c16
I reckon it stated off like Number 14 and someone extended it out with a ladder frame. If you don't want to strip the roof you could probably slowly jack it up with an acrow and reinforce with a length of unequal angle iron across the front, concealed by an additional piece of fascia.
