Is my shower riser too out of plumb for my Kerdi drain?

Sorry I was a bit rushed posting.
I just plumbed my basement bathroom and poured the slab and my the shower drain riser is a bit off from plumb.
It’s 2" solid-wall PVC and the riser is already glued into the P-trap below the slab. The trap arm maintains 1/4" per foot pitch and the riser is centered exactly where it needs to be for the Kerdi foam pan and drain.
The riser is plumb in one direction and exactly 1 degree out in the other. Once trimmed for the Kerdi drain, there will be roughly 6" of vertical riser between the trap and drain connection.
My main question is whether this small amount of error can normally be accommodated while solvent-welding the Kerdi drain and leveling the flange, or whether I should correct it some other way.

need to see more than the bubble can the pipe push over really easy or rock solid ?
Yes, I used a 4" coupler around the pipe.
I can provide torque that plumbs it but it's enough that it scares me that it's stressing the ptrap joint.
If you orient the p-trap just so, you could be stress-free. Now that may not be the direction you wanted the trap arm to go, but maybe you could bring that into closer alignment with a 22.5 or 45 bend. So maybe you don't quite get stress-free, but maybe stress-reduced.
I don't have an opinion on whether stress-reduction is worthwhile.
