On the Airbus a330-300 and a340-300, you can cleary see that there is a curve in the line of windows following door 3L/R. It is clearly evident in the following:

The cabin floor also curves up.
If you have never designed an airplane part before, let the real designers do the work!

It also did it on the A300 if I recall correctly.

I believe that design was to permit more full-size cargo containers to be carried on the lower deck. Doesn't make any difference to passengers (and it's hardly even noticeable in the cabin), but if the floor didn't have that slight curve you would lose several inches of height in the cargo compartment in that area.

The A300, A310, A330, and A340 all share the same fuselage mold lines, differing only in length. The noses and tail sections are all identical.
You are correct. As a consequence of the Airbus design, the rear cabin floor slopes up very slightly so as to accommodate more cans in the aft hold. The windows must slope up with the cabin or they would be next to the feet of the pax sitting in the very rear.
This will not be the case on the A350 and it is not the case on the A380.

I believe that's not correct for the original A300B2/B4 which had a different rear fuselage profile than the later A300-600R which used the same rear fuselage profile as the A310. That's quite obvious in photos.
