Acceptable Amount of Bend of Leadscrew?

Hi, I believe that one of my leadscrews has a slight bend, which can be seen when turning it. The first video is with the bed arm close to the bottom, the upper end of the leadscrew is uncontrained. Here you can see that the end of the leadscrew shifts position when rotated. The second video is with the bearing inserted into the leadscrew constraint, with the Bed arm at half height. Again, the leadscrew slightly moves within the opening of the bed arm. I think this leads to the conclusion, that the leadscrew is bent. Both other leadscrews don’t show such behavior. I am now wondering if this is still acceptable and can be ignored, or reason to ask for a replacement?
